Reaction Steps

A mixture of 5-bromomethyl-benzo[1,2,5]thiadiazole [RN65858-50-6](7.0 g, 30 mmol), ethanol (50 ml)and a solution of potassium cyanide (2.3 g, 36 mmol) in water (25 ml) was stirred at 50° C. for 15 hours. The alcoholic solution was concentrated and the residue suspended in water. The solid was collected by filtration, washed with water and dried in vacuo to give benzo[1,2,5]thiadiazol-5-yl-acetonitrile (2.8 g, 47%)
