2.4 g. 3-imino-1-phenyl-3H-1,2-benzisothiazole-1-oxide are boiled for 1 hour with 1.32 g. triethylamine and 1.6 g. phenylacetyl chloride in 50 cc. chloroform. After working up in the usual manner, there is obtained 3-(phenylacetylimino)-1-phenyl-3H-1,2-benzisothiazole-1-oxide in the form of yellow crystals which, after recrystallisation from ethyl acetate, melt at 120°C.
