ENJOY THE INTERPRETATIONS

Vilazodone (United States trade name Viibryd veye-brid) is a serotonergic antidepressant developed by Clinical Data for the treatment of major depressive disorder. The chemical compound was originally developed by Merck KGaA (Germany).[2] Vilazodone was approved by the FDA for use in the United States to treat major depressive disorder in 2011.[3][4][5]

Medical uses

According to two eight-week, randomized, double-blind, placebo-controlled trials in adults, vilazodone elicits an antidepressant response after one week of treatment. After eight weeks, subjects assigned to vilazodone 40 mg daily dose (titrated over 2 weeks) experienced a significantly higher response rate than the group given placebo (44% vs 30%, P = .002). Remission rates for vilazodone were not significantly different versus placebo.[6]

According to an article on the United States approval of vilazodone written by FDA staff, “it is unknown whether [vilazodone] has any advantages compared to other drugs in the antidepressant class.”[7]

PAPER FROM OPRD

Scale-Up Synthesis of Antidepressant Drug Vilazodone

Department of Medicinal Chemistry, China Pharmaceutical University, Nanjing, 210009, P. R. China
Org. Process Res. Dev., 2012, 16 (9), pp 1552–1557
DOI: 10.1021/op300171m
Abstract Image

A scale-up synthesis of antidepressant drug vilazodone was accomplished in five steps. Friedel–Crafts acylation of 1-tosyl-1H-indole-5-carbonitrile with 4-chlorobutyryl chloride, selective deoxygenation in NaBH4/CF3COOH system coupled with ethyl 5-(piperazin-1-yl)-benzofuran-2-carboxylate hydrochloride, one-step deprotection and esterolysis, and the final ammonolysis led to the target molecule vilazodone in 52.4% overall yield and 99.7% purity. This convenient and economical procedure is remarkably applicable for scale-up production.

5-(4-(3-(5-Cyano-1H-indol-3-yl)butyl)piperazin-1-yl)benzofuran-2-carboxamide (1)

To a solution of 6 (3 kg, 11.3 mol) in anhydrous DMF (150 L) at 15 °C was added CDI (1.6 kg, 10.2 mol). ……………………………………………….DELETED……………………to furnish the crude product of vilazodone hydrochloride 1 as off-white solid. The product of vilazodone hydrochloride was then recrystallized from an ethanol–methanol solution (1:1; 10 L) to give the final pure product vilazodone hydrochloride as white needles (2.4 kg, 81%). HPLC analysis: 99.7%. Mp: 234–236 °C (became charred).
