Canertinib (CI-1033) is an experimental drug candidate for the treatment of cancer. It is an irreversible tyrosine-kinase inhibitor with activity against EGFR (IC50 0.8 nM), HER-2 (IC50 19 nM) and ErbB-4 (IC50 7 nM).[1][2] By 2015, Pfizer had discontinued development of the drug.[3]

Canertinib has been reported as a substrate for OATP1B3. Interaction of canertinib with OATP1B3 may alter its hepatic disposition and can lead to transporter mediated drug-drug interactions.[4] Also, canertinib is not an inhibitor of OATP-1B1 or OATP-1B3 transporter.[5]

SYN

J Med Chem 2000,43(7),1380

EP 1131304; US 6344455; WO 0031048

4-Chloro-7-fluoro-6-nitroquinazoline (I) was condensed with 3-chloro-4-fluoroaniline (II) to afford the 4-anilino quinazoline (III). Displacement of the activated fluorine of (III) with the potassium alkoxide of morpholinopropanol (IV) gave the morpholinopropyl ether (V). Subsequent reduction of the nitro group of (V), either using iron dust and acetic acid or catalytic hydrogenation over Raney-Ni, furnished aminoquinazoline (VI). This was finally condensed with acrylic acid (VII), via activation as the mixed anhydride with isobutyl chloroformate or using EDC as the coupling reagent, to provide the title acrylamide.

[0005] China Patent No. CN1160338C, CN1438994A and No. No. CN1745073A reported the preparation of canertinib: A nucleus 4- [(3-chloro-4-fluorophenyl) amino] -6-nitro 7-fluoro-quinazoline (VIII) as a starting material, under basic conditions with 3- (4-morpholinyl) -1-propanol 7-position substitution reaction occurs to give 4- [(3-chloro – 4-fluorophenyl) amino] -6-nitro-7- [3- (4-morpholinyl) -1-propoxy] quinazoline (IX); intermediate (IX) through the 6-position nitro reduction, to give the corresponding amino compound (X); amino compound (X) to give canertinib acylation reaction (I) with acrylic acid or acryloyl chloride occurs.

[0006] In addition, “Qilu Pharmaceutical Affairs” 30, 2011, Vol. 10, page 559, and “China Industrial Medicine” 2010 Volume 41, No. 6, pp. 404 also reported an improved method of the above-prepared and studied method from 7-fluoro-quinazolin-3-one (V) via nitration, chloro and condensation reaction of the preparation of intermediate (VIII) is.

[0008] This shows that the current Kanai prepared for Nepal is mainly the 4-position through an intermediate (VII), respectively, a functional transformation of the 6-position and 7-position achieved. Since the intermediate (VII) a fluorine-containing compounds, materials are not readily available, many steps, and many steps are required to be isolated and purified by column chromatography, which is not required for industrialization.

Example a:

[0023] at room temperature, to a three-necked flask was added diisopropyl azodicarboxylate (3mL, 15mmol) and tetrahydrofuran 5mL, dropwise addition of triphenylphosphine (4.0g, 15mmol) in tetrahydrofuran 25mL solution at room temperature, kept at room temperature for 2 hours. Under nitrogen, 3- (4-morpholinyl) -1_-propanol (0.49g, 3.4mmol) in 5mL of tetrahydrofuran was added dropwise to the reaction system after the dropwise addition is complete, 6-amino – 7-hydroxy-3,4-dihydro-quinazolin-4-one (II) (0.53g,

3.0mmol), stirred at room temperature for 4 hours. Solution of 3- (4-morpholinyl) -1-propanol (0.38g, 2.6mmol) in 5mL of tetrahydrofuran was continued at room temperature for 2 hours, the end of the reaction was monitored TLC. Recovery of the solvent by distillation under reduced pressure, the residue was treated with dilute hydrochloric acid, pH = 5-6, extracted with ethyl acetate, the organic phase was washed with saturated sodium carbonate adjusted pH = 10-11. The aqueous phase was freeze-dried in vacuo to give an off-white solid 6-amino-7- [3- (4-morpholinyl) propoxy] _3,4- dihydroquinazolin-4-one (111) 0.80g yield 87.7%.

[0024] Example II:

[0025] to a three-neck flask was added 6-amino-7- [3- (4_ morpholino) propoxy] quinazolin-dihydro _3,4_ one _4_

(III) (0.76g, 2.5mmol), triethylamine (0.25g, 2.5mmol) and dichloromethane 20mL, warmed to 40-45 ° C, stirred until homogeneous dissolution system. Dropped below 10 ° C, was slowly added dropwise acryloyl chloride (0.25g, 2.8mmol) in dichloromethane IOmL solution dropwise at room temperature after continued for 6 h, TLC detection reaction was completed. The reaction solution was respectively 10% sodium bicarbonate solution and water, dried over anhydrous sodium sulfate. Recovery of the solvent under reduced pressure, the residue was recrystallized from ethyl acetate to give a white solid 7- [3- (4-morpholinyl) propoxy] -6-acrylamido-3,4-dihydro-quinazoline – 4-one (IV) 0.81g, 90.5% yield.

[0026] Example III:
