Reaction Steps
1 g of p-toluene sulfonic acid was added to a suspension of 1.5 g of 4-(4-chloro-3-sulfamoylphenyl)-3-methyl-2-methylimino-1,3-thiazolidine-4-ol in 10 ml of ethanol. The clear solution was poured into 60 ml of diisopropyl ether and the oil so obtained was recrystallized by treating with diethyl ether. Colorless crystals were obtained which were decomposed from 94° C onwards.
