Reaction Steps

The 2-fluoro-4-(1-phenoxyethyl)benzoic acid (150 mg, 0.514 mmol), 2-(7-Aza-1H-benzotriazole-1-yl)-1,1,3,3-tetramethyluroniumhexafluorophosphate (353 mg, 0.84 mmol) was dissolved in 20 mL dichloromethane, and then added triethylamine (2 mL). After the mixture was stirred at room temperature for 10 minute, 3-(aminomethyl)-4,6-dimethylpyridin-2-ol (0.514 mmol, 96 mg) was added. The mixture was stirred at room temperature for 12 hours then washed with water (10 mL), extracted with dichloromethane (20 mL). The organic layer were concentrated and s purified by column chromatography (silica gel, dichloromethane/methanol=20:1) to give 2-fluoro-N-((2-hydroxy-4,6-dimethylpyridin-3-yl)methyl)-4-(1-phenoxyethyl)benzamide (70 mg, 47%). LCMS (M+H+) m/z: calcd 394.17. found 394. 1H NMR (300 MHz, CD3OD) δ 7.69 (t, J=6.1 Hz, 1H), 7.28-7.13 (m, 4H), 6.86-6.81 (m, 3H), 6.06 (s, 1H), 5.43-5.41 (m, 1H), 4.47 (s, 2H), 2.34 (s, 3H), 2.22 (s, 3H). 1.57 (d, J=6.6 Hz, 3H).
