24 g. 3-imino-1-phenyl-3H-1,2-benzisothiazole-1-oxide, 13.2 g. triethylamine and 21 g. 4-chlorophenoxyacetyl chloride are heated under reflux for 1 hour in 1 liter chloroform. After working up the reaction mixture in the usual manner, there is obtained 3-(4-chlorophenoxyacetylimino)-1-phenyl-3H-1,2-benzisothiazole-1-oxide which, after recrystallisation from acetonitrile, is obtained in the form of colourless, felted needles melting at 196°C.
