A PROCESS FOR PREPARATION OF 2-(2,6-DICHLOROANILINO) PHENYL ACETOXY ACETIC ACID

摘要

Process for manufacture of 2-(2,6-dichlooranilino) phenyl acetoxy acetic acid is provided. The process comprises of acid hydrolysis 2-tert-butoxy-2-oxoethyl {2-[(2,6-dichlorophenyl)aminorophenyl}acetate in presence of a stron acid catinic exchange resin with SO3H group on - Divinylbenzene copolmer beads in presence of a solvent to yield compounds of the formul1. The compounds so obtained have shown non-steroidal anti-inflammatory activity.
