Reaction Steps
To a solution of 4-(3-methylbutan-2-yl)benzoic acid (0.10 g, 0.50 mmol), 1-Ethyl-(3-dimethylaminopropyl)carbodiimide hydrochloride (0.14 g, 0.7 mmol) and 1-hydroxybenzotriazole (0.10 g, 0.70 mmol) in dichloromethane (20 mL) was added triethylamine (0.2 g, 2.0 mmol). The reaction mixture was stirred at room temperature for 15 minutes, and followed by 3-(aminomethyl)-4,6-dimethylpyridin-2-ol (0.08 g, 0.5 mmol). The reaction mixture was stirred at room temperature for 12 hours. After the reaction, the mixture was washed with water, dried by anhydrous sodium sulfate, then the solvent removed in vacuo to give the crude product, which was purified by Prep-TLC (dichloromethane:methanol=20:1) to give the pure product N-((2-hydroxy-4,6-dimethylpyridin-3-yl)methyl)-4-(3-methylbutan-2-yl)benzamide (0.08 g, 44%) as a white solid. LR MS (M+H+): calcd for 326.2. found 326. HPLC Purity (214 nm) 99.6%. 1H NMR (CH3OH-d4, 300 MHz): δ 7.71 (d, J=8.1 Hz, 2H), 7.23 (d, J=8.4 Hz, 2H), 6.10 (s, 1H), 4.49 (s, 2H), 2.49-2.44 (m, 1H), 2.37 (s, 3H), 2.24 (s, 3H), 1.82-1.75 (m, 1H), 3.1˜43.06 (m, 1H), 1.24 (d, J=7.2 Hz, 3H), 0.96 (d, J=6.6 Hz, 3H), 0.76 (d, J=7.2 Hz, 3H).
