A Novel Process For Preparation Of Bicalutamide
Abstract: The present invention discloses a process for the synthesis of N-[4-Cyano-3-(trifluoromethyl) phenyl]-3-[(4-fluorophenyl) sulphonyl]-2-hydroxy-2-methyl propanamide (F0rm I). The invention discloses a novel reagent for oxidation of N-[4-Cyano-3-(trifluoromethyl) phelyl]- 3-[(4-fluorophenyl) thio]-2hydroxy-2methyl propanamide to N-[4-Cyano-3-(trifluoromethyl) phenyl]-3-[4-fluorophenyl) sulphonyl]-2-hydroxy-2-methyl propanamide. More particularly, the invention discloses a novel method of purification of N-[4-Cyano-3-(trifluoromethyl) phenyl]-3-[(4-fluorophenyl) sulphonyl]-2-hydroxy-2-methyl propanamide in a mixture of methylethyl ketone and hexane giving form (I). This form (I) is useful as an active pharmaceutical and has antiandrogenic activity.
