The mixture was stirred for 0.5 hour. Then 3-(aminomethyl)-4,6-dimethylpyridin-2-ol (120 mg, 0.8 mmol) was added and the mixture was stirred at room temperature for 4 hours. The mixture was washed with water (50 mL). The organic phase was separated and concentrated to give a residue. The residue was purified through column chromatography (silica gel, dichloromethane/methanol=20:1) and to afford N-((2-hydroxy-4,6-dimethylpyridin-3-yl)methyl)-4-(tetrahydrofuran-2-yl)benzamide (35 mg, 21%) as a white solid. LRMS (M+H+) m/z: calcd 326.16. found 326.
