Procedure

To ethyl (3S)-2-(methylsulfanyl)-3-(3,4,5-trifluorophenoxy)-3,4,5,6-tetrahydropyridine-3-carboxylate (702 mg) and 3 methoxy-4-(2-methyl-1,3-oxazol-5-yl)benzohydrazide (500 mg) was added acetic acid (3 mL), and the mixture was stirred at 100° C. for 3 hr. The reaction mixture was diluted with ethyl acetate, and the mixture was washed with 10% aqueous potassium carbonate solution and saturated brine, dried over anhydrous sodium sulfate, and purified by silica gel column chromatography (NH, ethyl acetate). The crudely-purified product was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (933 mg).
