2-Methyl-4-(phenoxymethyl)benzoic acid (42 mg, 0.17 mmol), o-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyfluoroniumhexafluorophosphate (99 mg, 0.26 mmol), triethylamine (0.1 mL) and dichloromethane (15 mL) were stirred at 25° C. for half hour. Then 3-(aminomethyl)-4,6-dimethylpyridin-2-ol (27 mg, 0.17 mmol) was added to the mixture. The mixture was stirred at 25° C. for 12 hours. The resultant mixture was washed with water (20 mL), dried over sodium, filtered, and concentrated to give a residue. The residue was purified by column chromatography (silica gel, dichloromethane/methanol=10:1) to give N-((2-hydroxy-4,6-dimethylpyridin-3-yl)methyl)-2-methyl-4-(phenoxymethyl)benzamide as a white solid (50 mg, 78%). LRMS (M+H+) m/z: calcd 376.18. found 376. HPLC purity (214 nm): 98%. 1H NMR (300 MHz, d6-DMSO): δ 11.46 (s, 1H), 8.11 (t, J=4.8 Hz, 1H), 7.28-7.20 (m, 5H), 7.00-6.84 (m, 3H), 5.86 (s, 1H), 5.07 (s, 2H), 4.27 (d, J=4.8 Hz, 2H), 2.31 (s, 3H), 2.19 (s, 3H), 2.11 (s, 3H).
