실험 절차

A mixture of 1-benzyl-5-methyl-1H-pyrazole-4-carboxylic acid (75 mg, 0.34 mmol), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (95 mg, 0.5 mmol), N-hydroxybenzotrizole (67 mg, 0.5 mmol), triethylamine (0.1 mL) and dichloromethane (5 mL) were stirred at 25° C. for 0.5 hours. Then 3-(aminomethyl)-4,6-dimethylpyridin-2-ol (50 mg, 0.33 mmol) was added. The mixture was stirred at 25° C. for 12 hours. To the mixture, water (10 ml) was added and the mixture was extracted with dichloromethane (10 mL×3). The combined organic phase was dried by sodium sulfate and then filtered. The filtrate was concentrated in vacuo. The residue was purified by column chromatography (silica gel, dichloromethane/methanol=20:1) to give 1-benzyl-N-((2-hydroxy-4,6-dimethylpyridin-3-yl)methyl)-5-methyl-1H-pyrazole-4-carboxamide as a white solid (35 mg, 29%). LRMS (M+H+) m/z: calcd 350.17; found 350. 1H NMR (300 MHz, d6-DMSO): δ 11.46 (s, 1H), 8.21 (s, 1H), 7.68 (t, J=5.1 Hz, 1H), 7.38-7.21 (m, 5H), 5.85 (s, 1H), 5.20 (s, 2H), 4.19 (d, J=5.4 Hz, 2H), 2.29 (s, 3H), 2.15 (s, 3H), 2.10 (s, 3H).
