U.S. patent publication no. 2008/0167337 discloses a process for the preparation of tetrabenazine compound of structural formula I wherein 6, 7-dimethoxy-3, 4-dihydroisoquinoline compound of structural formula VII is reacted with 3-dimethylaminomethyl-5-methyl-hexan-2-one methiodide compound of structural formula VIII to get crude tetrabenazine compound. The crude tetrabenazine compound was purified by employing flash column chromatography technique and

Formula VIII Formula I

The prior-art processes for preparing N-formyl-2-(3, 4-dimethoxyphenyl)-ethylamine compound of structural formula III produces below mentioned compound of structural formula XVII, XVIII, XIX, XX, XXI and XXII as a by-product of the reaction due to the demethylation and formylation of resulting hydroxy compounds.

Formula XX Formula XXI Formula XXII

The compounds of structural formula XVII, XVIII, XIX, XX, XXI and XXII are being carry- forwarded into the further steps of reactions of preparing tetrabenazine compound of structural formula I and therefore there is a need in the art to develop an improved process of preparing 6, 7-dimethoxy-3, 4-dihydroisoquinoline compound of structural formula VII, which obviates the prior-art problems. Accordingly there is provided a process of preparing tetrabenazine compound of structural formula I wherein 6, 7-dimethoxy-3, 4-dihydroisoquinoline compound of structural formula VII is being formed without the formation of above mentioned compounds of structural formula XVII, XVIII, XIX, XX, XXI and XXII.

EXAMPLE: PROCESS FOR THE PREPARATION OF SUBSTANTIAL PURE CRYSTALLINE FORM A OF TETRABENAZINE

Stage A: Process for the preparation of 6, 7-dimethoxy-3, 4-dihydroisoquinoIine

Step 1 : Process for the preparation of N-formyl-2-(3, 4-dimethoxyphenyl)-ethylamine

A solution of 2-(3, 4-dimethoxyphenyl)-ethylamine (500gm) in toluene (2000ml) was added formic acid (150gm) at 25°C, the resulting reaction mixture was diluted with toluene (500ml) and heated up to 45°C. The reaction mixture was maintained at 40-45°C for 5 hours and then the resulting reaction mixture was concentrated under reduced pressure at 50°C to get the title compound

Yield: 570gm

Purity: 99.98% (By HPLC)

Step 2: Process for the preparation of 6, 7-dimethoxy-3, 4-dihydroisoquinoline

A solution of N-formyl-2-(3, 4-dimethoxyphenyl)-ethylamine (250gm) obtained from step 1 in toluene (500ml) and polyphosphoric acid (50gm) was heated at 110°C for 5 hours. The resulting reaction mixture was cooled to 50°C, quenched with water (500ml) and pH of the resulting solution was adjusted to about 8.3 with aqueous solution of sodium hydroxide [sodium hydroxide (690gm) + water (690ml)]. The resulting reaction mass was extracted by ethyl acetate (2 1250ml), dried over anhydrous sodium sulfate (50gm) and concentrated under reduced pressure to get 6, 7-dimethoxy-3, 4-dihydroisoquinoline (190gm).

Yield: 215gm

Purity: 99.67% (By HPLC)

The resulting reaction mixture was stirred at 25 °C for 12 hours and then the resulting solids were filtered, washed with water (200ml) and suck-dried to get wet compound (400gm). The wet compound was slurried with water (1000ml) at 25°C for 1 hour and then it was again filtered, washed with water (200ml) and dried at 45-50°C to get title compound

Yield: 300gm

Purity: 99.86% (By HPLC)

The TBZ (4) for these reactions was prepared by reacting 3,4-dihydro-6,7-dimethoxyisoquinoline (3) and the Mannich base (2) as shown in Scheme 1.14 The α,β-unsaturated TBZ (5), which was the original substrate, was obtained by further treatment with chloranil in refluxing benzene.

Tetrabenazine (4a)

To a solution of 3,4-dihydro-6,7-dimethoxyisoquinoline hydrochloride (3, 3.5 g, 15.4 mmol) in cold H2O (20 mL) in an ice water bath, was added 3-(dimethylaminomethyl)-5-methyl-2-hexanone (2, 3.15 g, 18.3 mmol) as the free base with stirring. Precipitate formed within 3 h, and stirring was continued until the solid-gummy precipitate prevented stirring. The mixture was allowed to stand at RT (room temperature) for 3 days. The solid–gum mixture was filtered, and the yellow solid–gum mixture was dissolved in hot MeOH. The solution was chilled at −10°C for 18 h. The pale yellow solid was filtered to give 2.1 g (43%) of TBZ (4a).

Example 10 Removal The Boc Protecting Group From First Intermediate 12 And Amino Cyclization Provide (+)-Tetrabenazine XVII

[0063] First intermediate 12 (1.0 eq) was dissolved in 10% Me2S- dichloromethane to provide an 82 mM solution. The solution was cooled to 0 0C and triisopropylsilane (1.1 eq.) followed by TFA (precooled to 0 0C) was added to the reaction mixture to provide a final concentration of 41 mM. The reaction mixture was permitted to stir at 0 0C for 1 h. Following the allotted time the reaction mixture was quenched at 0 0C by the addition of saturated aqueous potassium carbonate solution and concentrated under reduced pressure to remove the majority of the dimethylsulfide. The mixture was extracted with five portions of dichloromethane, and the combined organic extracts were washed with brine, dried (MgSO4), filtered and concentrated under reduced pressure to provide the crude product as a yellow solid. The crude product was recrystallized from 3.5% dimethoxyethane in hexanes. The resulting colorless crystals were washed with hexanes to provide pure (+)- tetrabenazine (XVII) 46%: mp 126.0 0C (3.5% DME-hexanes) (a crystal polymorph was observed at 116 0C); [α]26 D +37.2 (c 0.41, CH2Cl2); 1H NMR (CD2Cl2) δ 0.89 (apparent t, J = 7.2 Hz, 6H), 0.98 (ddd, J = 12, 6.0, 4.0 Hz, IH), 1.59-1.68 (m, IH), 1.74 (ddd, J = 12, 5.9, 5.7 Hz, IH), 2.32 (apparent t, J = 11.7 Hz, IH), 2.46 (apparent t, J = 12.3 Hz, IH), 2.55 (ddd, J = 12, 10.0, 3.8 Hz, IH), 2.65-2.73 (m, 2H), 2.83 (dd, J = 5.5, 2.8Hz, IH), 2.97-3.07 (m, IH), 3.07-3.14 (m, IH), 3.25 (dd, J =9.7, 6.3 Hz, IH), 3.47 (apparent d, J = 12Hz, IH), 3.75 (s, 3H), 3.77 (s, 3H), 6.55 (s, IH), 6.60 (s, IH) 13C NMR (CD2Cl2) δ 21.98, 23.02, 25.51, 29.46, 35.16, 47.47, 47.63, 50.47, 55.87, 56.01, 61.47, 62.46, 108.46, 111.72, 126.37, 128.96, 147.65, 147.98, 209.72; HRMS-(ESI+) calcd for (C19H27NO3 + H) ([M+H]+ 318.2069, found 318.2082.

Abstract

Abstract Image

A novel process for the synthesis of tetrabenazine (1) and deutetrabenazine (2), two well-known drugs used for the treatment of chorea associated with Huntington’s disease, has been developed. All of the reaction parameters were optimized through a series of reactions and by using Design of Experiment techniques. The newly developed methods are industrially scalable and employ cheap, commercially available raw materials and hence are highly efficient. The added advantage is that the developed processes evade the use of genotoxic alkylating agents and therefore could be considered as safe and viable alternatives to the existing methods.

Tetrabenazine (1) was invented by Hoffmann-La-Roche (Nutley, NJ, USA). It was also known as Ro 1-9569, Nitoman, and Xenazine. It is a benzoquinolizine derivative with the chemical name 1,3,4,6,7,11b-hexahydro-9,10-dimethoxy-3-(2-methylpropyl)-2H-benzo[α]quinolizin-2-one . Initially it was developed as an antipsychotic agent.Despite 50 years of medicinal background, the U.S. Food and Drug Administration (FDA) approved 1 on August 15, 2008, for the treatment of chorea associated with Huntington’s disease.

Deutetrabenazine (2) (trade name Austedo) is a stable, nonradioactive deuterium analogue of the approved drug tetrabenazine in which the six hydrogen atoms of the 9- and 10-methoxy (−OCH3) substituents have been replaced by deuterium atoms . Deutetrabenazine was found to be more effective for the treatment of chorea associated with Huntington’s disease because of improved pharmacokinetic properties compared with the nondeuterated drug tetrabenazine. Deutetrabenazine was originally developed by Auspex Pharmaceuticals (La Jolla, CA, USA). In 2015, Teva acquired Auspex Pharmaceuticals and submitted a new drug application (NDA) in the United States for the treatment of Huntington’s disease. On April 3, 2017, Teva Pharmaceutical received approval from the FDA to market deutetrabenazine as the first deuterated drug for the treatment of chorea associated with Huntington’s disease.(4) Both 1 and 2 are racemic mixtures .
