Procedure
68 g of 4-methylsulfonyltoluene in 400 ml of concentrated sulfuric acid were admixed at 0°-10° C. with a mixture of 80 ml of concentrated sulfuric acid and 31 ml of 65% strength by weight nitric acid. The reaction mixture was stirred at 10° C. for 2 hours and at room temperature for a further 2 hours. It was then poured onto about 1 kg of ice, and the solids were filtered off with suction, washed with water and dried at 50° C. under reduced pressure, to leave 85 g of 4-methylsulfonyl-2-nitrotoluene (melting point 112°-115° C.).
