Water → 2-(2-Nitrophenylthio)benzonitrile

Participants

Reaction Steps

In a mixture of 12.7 g of pyridine and 80 ml of dioxane was suspended 8.8 g of 2-(2-nitrophenylthio)benzamide, followed by dropwise addition of 10.1 g of trifluoroacetic anhydride with ice-cooling, and the mixture was stirred for 1 hour. To the reaction mixture was added water and the crystals separated out therefrom were collected by filtration, washed with water and hot ethanol and dried. The procedure gave 7.84 g of the title compound as yellow crystals, m.p. 166°-167° C.
