Analogously to Example A, equimolar amounts of 4-aminotetrahydrothiopyran (prepared from tetrahydrothiopyran-4-one via the corresponding oxime and subsequent reduction with lithium aluminum hydride in tetrahydrofuran) and 4-trifluoromethylnicotinoyl chloride were reacted in the presence of triethylamine. This gave, after silica gel chromatography (ethyl acetate), the amide as a colorless solid of melting point 161-163° C. (Yield 51.3% of theory).
