A mixture of 37.2 g of benzylmercaptan, 36.3 g of 4-fluorobenzonitrile and 42 g of potassium carbonate in 700 ml of butan-2-one is held under reflux for 7 hours. The solvent is evaporated in vacuo, the residue is taken up into water and petroleum ether. The crystals formed are filtered off, washed with water and petroleum ether to give 46 g of 4-benzylthiobenzonitrile as crystals with a melting point of 85° C.
