Procedure

To a solution of 4-(2-hydroxypropan-2-yl)benzoic acid (0.09 g, 0.5 mmol) and O-(7-Azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (0.23 g, 0.61 mmol) in dichloromethane (10 mL) was added triethylamine (0.15 g, 1.5 mmol). The reaction mixture was stirred for 15 minutes at room temperature, then 3-(aminomethyl)-4,6-dimethylpyridin-2-ol (0.08 g, 0.53 mmol) was added. The reaction mixture was stirred at room temperature for 12 hours. After the reaction, the mixture was washed with water (20 mL), concentrated and purified by column chromatography (silica gel:dichloromethane:methanol=30:1) to give the pure product (0.11 g, 76%) as a white solid. LRMS (M+H+) m/z: calcd for 314.16. found 314. HPLC Purity (214 nm) 100%. 1H NMR (300 MHz, DMSO-d6) δ: 11.47 (s, 1H), 8.28-8.26 (m, 1H), 7.76 (d, J=8.4 Hz, 2H), 7.49 (d, J=8.7 Hz, 2H), 5.86 (s, 1H), 5.08 (s, 1H), 4.29 (d, J=4.8 Hz, 2H), 2.17 (s, 3H), 2.11 (s, 3H), 1.41 (s, 6H).
