Reaction Steps

Isonicotinoyl chloride hydrochloride (172 mg, 0.966 mmol, commercially available product), triethylamine (340 μl, 2.44 mmol), and a catalytic amount of 4-(dimethylamino) pyridine were sequentially added at room temperature to a dichloromethane (5 ml) solution of 5-methyl-2-(1-piperidinyl)aniline (155 mg, 0.815 mmol), obtained as described in Referential Example 16-2. The resulting mixture was stirred for 19 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 (10 g, hexane/ethyl acetate=1/1). Thus, N-[5-methyl-2-(1-piperidinyl)phenyl]isonicotinamide (GIF-0342) (69.5 mg, 28.8%) was yielded as a colorless solid.
