1.7 g of 80% m-chloroperbenzoic acid was added to a solution of 2.0 g of [{1-(6-methyl-1,3-benzodioxol-5-yl)ethyl}thio]acetic acid in 40 ml of chloroform under cooling with ice. The mixture was stirred at room temperature overnight and a crystalline insoluble matter was recovered by filtration and washed with ether to obtain 0.24 g of the intended compound (as a single diastereomer) in the form of white crystals.
