Participants

Reaction Steps

To a solution of 1.51 g of ethyl 4-[2-(2-cyanophenylthio)phenylcarbamoyl]phenoxyacetate (prepared in accordance with Reference Example 6, Step 2) in 5 ml of chloroform was added dropwise a solution of 0.87 g of 70% m-chloroperbenzoic acid in 20 ml of chloroform and the mixture was stirred at room temperature for 2 hours. The reaction mixture was then washed with aqueous sodium hydrogen carbonate solution and dried over magnesium sulfate and the solvent was distilled off. The residue was recrystallized from ethyl acetate-n-hexane to give 1.3 g of the title compound as white crystals, m.p. 128°-130° C. .
