Procedure

Isonicotinoyl chloride hydrochloride (454 mg, 2.55 mmol, commercially available product) and triethylamine (385 μl, 3.83 mmol) were sequentially added at 0° C. to a dichloromethane (10 ml) solution of 5-fluoro-2-(1-piperidinyl)aniline (248 mg, 1.27 mmol), obtained as described in Referential Example 17-2. The resulting mixture was warmed to room temperature and stirred for 17 hours. Water was added to the mixture, and the resulting mixture was extracted three times with ethyl acetate. 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 (15 g, hexane/ethyl acetate=1.5/1). Thus, N-[5-fluoro-2-(1-piperidinyl)phenyl]isonicotinamide (GIF-0348) (257 mg, 67.6%) was yielded as a colorless solid.
