Abstract

The present invention relates to a process for preparation of substantially pure Vilazodone Hydrochloride and also relates to an isolated impurity of Vilazodone. The said process for producing Vilazodone, 1-[4-(5-cyanoindol-3-yl) butyl]-4-(2-carbonyl benzofuran-5-yl) piperazine represented by formula (1) or a pharmaceutically acceptable salt thereof comprises condensing the compound of formula (2) With a compound of formula (3) in an alcoholic solvent to obtain a white to yellow solid; isolating the solid obtained therefrom; slurry washing the solid obtained with water miscible solvent; dissolving the solid obtained therefrom in an amide solvent to obtain a solution; adding an aqueous solution of sodium metabisulphite and an inorganic base to the solution obtained to obtain the compound of formula (1) and optionally converting the solid obtained in step (v) to its pharmaceutically acceptable salt.
