Procedure

To a solution of (S)-2-methyl-4-(1-phenoxyethyl)benzoic acid (5.3 g, 19.5 mmol) in dichloromethane (100 mL) was added 2-(7-aza-1H-benzotriazole-1-yl)-1,1,3,3-tetramethyluronium hexafluorophosphate (11.1 g, 29.3 mmol) and triethylamine (8.6 mL, 62.2 mmol). The mixture was stirred at room temperature for 30 minutes. Then 3-(aminomethyl)-4,6-dimethylpyridin-2-ol (3.15 g, 21 mmol) was added and the mixture was stirred at room temperature for 12 hours. The mixture was poured into water (100 mL) and extracted with dichloromethane (50 mL*2). The combined organic phase was separated, dried by sodium sulphate, filtered and concentrated to give a residue. The residue was purified by column chromatography (silica gel, methanol/dichloromethane=1:10) to give (S)—N-((2-hydroxy-4,6-dimethylpyridin-3-yl)methyl)-2-methyl-4-(1-phenoxyethyl)benzamide (Compound I-55) as a white solid (4.5 g, 59%). LRMS (M+H+) m/z: calcd 390.19. found 390. HPLC purity (214 nm): 100%. 1H NMR (300 MHz, CD3OD): δ 7.28-7.22 (m, 3H), 7.12-7.09 (m, 2H), 6.83-6.79 (m, 3H), 6.10 (s, 1H), 5.36-5.34 (m, 1H), 4.44 (s, 2H), 2.36 (s, 3H), 2.33 (s, 3H), 2.23 (s, 3H), 1.57 (d, J=6.6 Hz, 3H).
