Hydrolysis of chlorimuron-ethyl at pH < 8 resulted in the breaking of urea bridge with formation of pyrimidinamine in quantitative yields. Phenyl sulfonamide ethyl ester generally was obtained in less amount as it got easily cyclised to saccharin (pH >6). In alkaline medium hydrolysis of carboethoxy group was preferential reaction.
