実験手順
99.6 Grams of 5-chloro-6-chlorosulfonyl-1-indanone are introduced portionwise into 700 ml of liquid ammonia. The solvent is allowed to evaporate and the residue is dissolved in water, is heated within a short time on the water-bath and is filtered after the addition of active charcoal. The solution is acidified with hydrochloric acid to a pH of 2, the precipitate is filtered off with suction and is washed with water. The melting point of 5-chloro-6-sulfamoyl-1-indanone is in the range of from 205° to 208° C., and after recrystallization from a mixture of acetone and water it is 216° to 218° C.
