Procedure

Isonicotinoyl chloride hydrochloride (704 mg, 3.95 mmol, commercially available product) and triethylamine (823 μl, 5.94 mmol) were sequentially added at 0° C. to a dichloromethane (6 ml) solution of 1-[2-amino-4-(trifluoromethyl)phenyl]-hexahydro-1H-azepine (512 mg, 1.98 mmol), obtained as described in Referential Example 4-2. The resulting mixture was stirred for one and a half hours. Water was added to the mixture, and the resulting mixture was extracted three times with dichloromethane. The obtained organic layer was washed with a saturated sodium chloride solution, dried over anhydrous sodium sulfate, filtered, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (30 g, hexane/ethyl acetate=2/1). Thus, N-[2-(1-hexahydro-1H-azepinyl)-5-(trifluoromethyl)phenyl]isonicotinamide (GIF-0618) (697 mg, 97.0%) was yielded as a colorless solid.
