Procedure

A mixture solution of 4-(1-phenoxypropan-2-yl)benzoic acid (60 mg, 0.2 mmol), 3-(aminomethyl)-4,6-dimethylpyridin-2-ol (37 mg, 0.2 mmol), 1-Hydroxybenzotriazole (30 mg, 0.2 mmol), 1-(3-Dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (40 mg, 0.2 mmol) and triethylamine (0.1 mL) in dichloromethane (50 mL) was stirred at room temperature for 18 hours. The mixture solution was diluting with ethyl acetate (50 mL), washed with water (20 mL). The organic layer was concentrated to dry. The residue was purified by column chromatography (silica-gel, dichloromethane/methanol=30:1) to give 4-(1-phenoxypropan-2-yl)-N-((2,4,6-trimethylpyridin-3-yl)methyl)benzamide as a yellow solid (60 mg, 64%). LRMS (M+H+) m/z: calcd 391.19. found 391.
