反応手順

To 20 ml of an acetic acid solution containing 3.4 g of N-(2-cyclohexyloxyphenyl)methanesulfonamide was added dropwise 1.5 g of 61% nitric acid on heating at 110° C. over a 30-minute period, and then the mixture was stirred for 1 hour. The reaction solution was poured into ice water and neutralized with a dilute aqueous sodium hydroxide solution. The crystals which formed were collected by filtration, washed with water and dried to give 4.5 g of the crude crystals, which were then recrystallized from ethanol-n-hexane to give 3.3 g of N-(2-cyclohexyloxy-4-nitrophenyl)methanesulfonamide.
