Procedure

S-(2,4,5-Trichlorophenyl) 4-(hydroxy)thiobenzoate (5.4 g) in dry chloroform (70 ml) at -20° C. was treated sequentially with sodium hydroxide (0.78 g) in water (3 ml) and thiophosgene (1.85 ml). The solution was allowed to warm to room temperature and was stirred for a further 2 hours. The reaction mixture was then dried over calcium chloride and the filtered solution evaporated to give a crude solid. Purification by chromatography on silica gel using ethyl acetate/hexane mixtures as eluants afforded 3.4 g of the title compound.
