Procedure

A solution of 7.8 g. of 4-(α-chloroethyl)thiazole is added dropwise to a suspension of 5.2 g. of sodium cyanide in 100 ml. of dimethylsulfoxide. The mixture is heated at 50°C. for 2 hours, then diluted with 150 ml. of a 5 percent aqueous sodium carbonate solution and extracted with ether. The extract is dried and concentrated to give α-(4-thiazolyl)propionitrile.
