Procedure

To a solution of 4-(1-(pyrimidin-2-yloxy)ethyl)benzoic acid (100 mg, 0.41 mmol), 1-hydroxybenzotriozole (83 mg, 0.61 mmol), 1-(3-Dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (118 mg, 0.61 mmol), triethylamine (0.2 mL) in dichloromethane (15 mL) was added 3-(aminomethyl)-4,6-dimethylpyridin-2-ol (62 mg, 0.41 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 N-((2-hydroxy-4,6-dimethylpyridin-3-yl)methyl)-4-(1-(pyrimidin-2-yloxy)ethyl)benzamide as a white solid (50 mg, 32%). LRMS (M+H+) m/z: 378.17. found 378. HPLC Purity (214 nm): 100%. 1H NMR (300 MHz, d6-DMSO): δ 11.46 (s, 1H), 8.30 (d, J=4.8 Hz, 1H), 8.06-8.04 (m, 1H), 7.80-7.68 (m, 2H), 7.44-7.42 (m, 2H), 6.93-6.84 (m, 2H), 6.17 (q, J=6.6 Hz, 1H), 5.84 (s, 1H), 4.27 (d, J=4.8, 2H), 2.15 (s, 3H), 2.11 (s, 3H), 1.55 (d, J=6.6 Hz, 3H).
