Procedure

To a solution of 4-(1-acetamidoethyl)benzoic acid (414 mg, 2.0 mmol), 1-hydroxybenzotriozole (405 mg, 3.0 mmol), 1-(3-Dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (576 mg, 3.0 mmol), triethylamine (0.83 mL) in dichloromethane (30 mL) was added 3-(aminomethyl)-4,6-dimethylpyridin-2-ol (82 mg, 0.54 mmol). The reaction mixture was stirred at 20° C. for 13 hours. The mixture was washed with water (20 mL×2). The organic phase was dried over sodium sulfate and filtered. The filtrate was concentrated. The residue was purified by column chromatography (silica gel, dichloromethane/methanol=10:1) to give 4-(1-acetamidoethyl)-N-((2-hydroxy-4,6-dimethylpyridin-3-yl)methyl)benzamide as a white solid (250 mg, 37%). LRMS (M+H+) m/z: calcd 341.17. found 341. HPLC Purity (214 nm): 98%. 1H NMR (300 MHz, d6-DMSO): δ 11.46 (s, 1H), 8.35-8.26 (m, 2H), 7.76 (d, J=8.4 Hz, 2H), 7.31 (d, J=8.4 Hz, 2H), 5.85 (s, 1H), 4.90 (q, J=7.2 Hz, 1H), 4.28 (d, J=5.1 Hz, 2H), 2.16 (s, 3H), 2.11 (s, 3H), 1.83 (s, 3H), 1.1 (d, J=7.2 Hz, 3H).
