Participants

Reaction Steps

18.4 g of 7-chloromethylbenzo-1,2,3-thiadiazole are dissolved in 50 ml of chloroform, 0.5 g of tetrabutylammonium iodide are added, the mixture is heated to 50°-55° C. and treated dropwise in the course of 0.5 hours with a solution of 5.6 g of sodium cyanide in 20 ml of water, with stirring. Heating is continued overnight at the same temperature, on the following day the mixture is cooled, treated with water and extracted several times using dichloromethane. The extracts are washed with water, dried over sodium sulfate and filtered over Hyflo, and the filtrate is evaporated. The residue is purified on silica gel (hexane/ethyl acetate) resulting in the title compound of m.p. 78°-80° C.
