Versuchsvorschrift

To a stirring solution of methyl 4-nitrophenyl sulfide (10 g, 59.1 mmol) in chloroform at 0° C. was added m-chloroperoxybenzoic acid (55.6 g, 177.3 mmol). After 3 h, ethyl acetate (1.2 L) was added followed by satd aq sodium bisulfite. After stirring overnight, the layers were separated and the organic phase was washed with satd ag sodium bicarbonate (3×200 mL), followed by brine, and then dried over MgSO4, filtered and concentrated in vacuo to give 11.27 g (95%) of the title compound.
