16 g (0.15 mol) of chloromethyl thiocyanate were added dropwise to 31.5 g (0.15 mol) of the K salt of 4-chlorothiobenzoic acid in 200 ml of methanol at 0°-10° and the mixture was then first warmed to room temperature and then to 50°-60°, until the reaction had taken place. The cooled mixture was poured onto 1 liter of cold water, whilst stirring vigorously, and the precipitate was filtered off and dried. Light pink-coloured crystals.
