Reaction Steps
4-Phenoxybenzoic acid (214 mg, 1.0 mmol), 1-hydroxybenzotriazole (203 mg, 1.5 mmol), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (290 mg, 1.5 mmol) and triethylamine (0.7 mL, 5 mmol) were dissolved in dichloromethane (15 mL). The mixture was stirred at room temperature for 0.5 hour. Then 3-(aminomethyl)-4,6-dimethylpyridin-2-ol (190 mg, 1.0 mmol) was added to the solution. The mixture was stirred at room temperature for 12 hours. After the reaction, the mixture was concentrated and the residue was purified by column chromatography (silica gel, dichloromethane/methane=40:1) to give the product as a white solid (120 mg, 34%). LRMS (M+H+) m/z: calcd 348.15. found 348. 1H NMR (300 MHz, d6-DMSO): δ 11.46 (s, 1H), 8.28 (m, 1H), 7.86 (s, 1H), 7.83 (s, 1H), 7.40 (t, J=7.2 Hz, 2H), 7.18 (t, J=7.5 Hz, 1H), 7.06 (s, 1H), 7.03 (s, 1H), 6.98 (s, 1H), 6.95 (s, 1H), 5.84 (s, 1H), 4.27 (d, J=7.5 Hz, J=3.6, 2H), 2.15 (s, 3H), 2.09 (s, 3H).
