Reaction Steps

To the solution of 4-(1-(o-tolyloxy)ethyl)benzoic acid (124 mg, 0.48 mmol) in dichloromethane (80 mL) was added o-(7-Azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (274 mg, 0.72 mmol) and triethylamine (145 mg, 1.44 mmol). then the 3-(aminomethyl)-4,6-dimethylpyridin-2-ol (73 mg, 0.48 mmol) was added, the solution was stirred at room temperature for 12 hours, then washed with water (50 mL*3), the organic layer was evaporated and purified by column chromatography (silica gel, dichloromethane/meth anol=20:1) to give N-((2-hydroxy-4,6-dimethylpyridin-3-yl)methyl)-4-(1-(m-tolyloxy)ethyl)benzamide (57 mg, 30%). LRMS (M+H+) m/z: calcd: 390.19. found 390; 1H-NMR (300 MHz, CD3OD) δ 7.75 (d, J=8.4 Hz, 2H), 7.45 (d, J=8.4 Hz, 2H), 7.71-7.08 (m, 1H), 6.97-6.92 (m, 1H), 6.77-6.66 (m, 2H), 6.10 (s, 1H), 5.46-5.44 (m, 1H), 4.48 (s, 2H), 2.36 (s, 3H), 2.28 (s, 3H), 2.24 (s, 3H), 1.62 (d, J=6.3 Hz, 3H).
