Versuchsvorschrift

To 20 ml of a pyridine solution containing 2.7 g of 2-cyclohexyloxyaniline was added dropwise 1.8 g of methanesulfonyl chloride under ice cooling with stirring. After completion of the addition, the mixture was stirred at room temperature for 2 hours. The reaction solution was poured into ice water and made acidic with dilute hydrochloric acid. The crystals which formed were collected by filtration, washed with water and dried to give 3.8 g of the crude crystals, which were then recrystallized from ethanol-n hexane to give 3.4 g of N-(2-cyclohexyloxyphenyl)methanesulfonamide.
