Procedure

A solution of 3-chloro-4-(2-cyanophenoxy)benzoic acid (100 mg, 0.37 mmol) in dichloromethane (20 mL) was added 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (91 mg, 0.48 mmol), N-hydroxybenzotriazole (65 mg, 0.48 mmol) and triethylamine (104 mg, 0.7 mmol), stirred for 30 minutes. Then 3-(aminomethyl)-4,6-dimethylpyridin-2-ol (56 mg, 0.37 mmol) was added and the mixture was stirred at room temperature for 12 hours. The mixture was washed with water (50 mL). The residue was purified by column chromatography (silica gel, dichloromethane/methanol=20:1) to afford 3-chloro-4-(2-cyanophenoxy)-N-((2-hydroxy-4,6-dimethylpyridin-3-yl)methyl)benzamide (34 mg, 58%) as white solid. LRMS (M+H+) m/z: calcd 407.1. found 407; 1H-NMR (300 MHz, CD3OD) δ 11.47 (s, 1H), 8.53 (m, 1H), 8.14 (d, J=2.1 Hz, 1H), 7.90 (m, 2H), 7.68 (m, 1H), 7.29 (m, 2H), 6.93 (d, J=0.9 Hz, 1H), 5.86 (s, 1H), 4.29 (d, 2H, J=4.8 Hz), 2.17 (s, 3H), 2.11 (s, 3H).
