From 12 g. 3-imino-1-phenyl-3H-1,2-benzisothiazole-1-oxide, 5 g. propionyl chloride and 6.6 g. triethylamine in chloroform, there is obtained, after heating under reflux for 3 hours and then working up the reaction mixture in the usual manner, the desired 3-(propionyl-imino)-1-phenyl-3H-1,2-benzisothiazole-1-oxide which, after recrystallisation from ethyl acetate, melts at 170°C.
