To a suspension of (3-chloro-5-trifluoromethyl-2-pyridyl)methylamine hydrochloride (0.12 g) and 2-chlorophenylisothiocyanate (0.09 g) in dry tetrahydrofuran (10 ml) was added 10 drops of triethylamine. The mixture was stirred at room temperature overnight. The solvent was removed by evaporation in vacuo and the residue extracted with ethyl acetate and washed with 2M hydrochloric acid. The layers were separated and the organic phase was evaporated to dryness to give the title product, m.p. 126° C.
