Reaction Steps

A solution of 4-(1-isobutoxyethyl)benzoic acid (132 mg, 0.59 mmol) in dichloromethane (50 mL) was added 2-(7-aza-1H-benzotriazole-1-yl)-1,1,3,3-tetramethyluronium hexafluorophosphate (35 mg, 0.5 mmol), triethylamine (32 mg, 0.7 mmol), stirred for 30 minutes. Then 3-(aminomethyl)-4,6-dimethylpyridin-2-ol (27 mg, 0.4 mmol) was added and the mixture was stirred at room temperature for 12 hours. The mixture was washed with water (50 mL), dried over sodium sulphate, concentrated. The residue was purified through column chromatography (silica gel, dichloromethane/methanol=20:1) to give the product N-((2-hydroxy-4,6-dimethylpyridin-3-yl)methyl)-4-(1-isobutoxyethyl)benzamide (83 mg, 40%) as white solid. LRMS (M+H+) m/z: calcd 356.13. found 356. HPLC Purity (214 nm): 97%. 1H NMR (300 MHz, CD3OD) δ 7.76 (d, J=8.1 Hz, 2H), 7.38 (d, J=8.1 Hz, 2H), 6.10 (s, 1H), 4.49-4.43 (m, 3H), 3.14-3.00 (m, 2H), 2.37 (s, 3H), 2.24 (s, 3H), 1.84-1.79 (m, 2H), 1.39 (d, J=6.3 Hz, 3H), 0.88 (d, J=6.6 Hz, 6H).
