実験手順

Similar process for the preparation of vilazodone is also reported in Journal of Medicinal Chemistry, 2004, Vol. 47, No. 19, pages 4684-4692 (hereinafter referred to as the ‘JMC article’). As per the process reported in the JMC article (see column-1 of Page No. 4690), the vilazodone is prepared by reacting 5-[4-[4-(5-cyano-1H-indol-3-yl)butyl]piperazin-1-yl]benzofuran-2-carboxylic acid with 2-chloro-1-methylpyridinium iodide in the presence of N-methylpyrrolidone to produce a reaction mass, followed by drop wise addition of ethyldiisopropyl amine while introducing ammonia gas and subsequent work up to produce vilazodone. The resulting vilazodone free base is then converted into its hydrochloride salt by dissolving vilazodone free base in hot 2-propanol to form a solution, followed by slow addition of HCl-saturated 2-propanol at room temperature until complete precipitation occurs to yield vilazodone hydrochloride (Melting Point: 277-279° C.).
