Procedure

To a solution of 25 g of 3,4-difluorobenzonitrile in 100 ml of N,N-dimethylformamide is added 25 g of potassium carbonate and 22.3 g of benzylmercaptan. The mixture is stirred for 3 hours at room temperature and water is added. The crystals are filtered off, washed with water and pentane and dried to give 41 g of 4-benzylthio-3-fluorobenzonitrile in the form of crystals melting at 87° C.
