実験手順
18 gm (0.07 mol) of the compound obtained in step (a) were suspended in 200 ml of concentrated ammonia, and the suspension was stirred at room temperature for 4 hours. Thereafter, the mixture was suction-filtered, the filter cake was washed with water, and the desired sulfonamide was obtained as an amorphous product after drying. Rf -value (benzene/acetone = 1/1): 0.6.
