10.0 g (35.3 mmol) of chloramine-T trihydrate (Aldrich) are added to 5.0 g (29.6 mmol) of 1-methylsulphanyl-4-nitrobenzene in 120 ml of acetonitrile at room temperature. The mixture is stirred at room temperature for 4 hours and then diluted with ethyl acetate. The mixture is filtered with suction and the filter cake is washed with ethyl acetate. The combined organic phases are dried (Na2SO4), filtered and concentrated. The resulting residue is recrystallized from methanol. 2.2 g (6.5 mmol; yield: 22%) of the product are obtained.
