Procedure

A mixture of 4-(1-phenoxypropyl)benzoic acid (256 mg, 1.0 mmol), o-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluroniumhexafluorophosphate (570 mg, 1.5 mmol), triethylamine (0.45 mL) and dichloromethane (15 mL) were stirred at 25° C. for half an hour. Then 3-(aminomethyl)-4,6-dimethylpyridin-2-ol (152 mg, 1.0 mmol) was added. The mixture was stirred at 25° C. for 12 hours. The mixture was washed with water (20 mL), dried over sodium, filtered and concentrated to give a residue. The residue was purified by column chromatography (silica gel, dichloromethane/methanol=10:1) to give N-((2-hydroxy-4,6-dimethylpyridin-3-yl)ethyl)-4-(1-phenoxypropyl)benzamide (Compound I-44) as a white solid (125 mg, 32%). LRMS (M+H+) m/z: calcd 390.19. found 390. HPLC purity (214 nm): 95%. 1H NMR (300 MHz, d6-DMSO): δ 11.44 (s, 1H), 8.28 (t, J=5.1 Hz, 1H), 7.78 (d, J=8.4 Hz, 2H), 7.42 (d, J=8.4 Hz, 2H), 7.17 (t, J=8.0 Hz, 2H), 6.87-6.83 (m, 3H), 5.84 (s, 1H), 5.27 (t, J=6.0 Hz, 1H), 4.27 (d, J=5.1 Hz, 2H), 2.68 (s, 3H), 2.51 (s, 3H), 1.89-1.80 (m, 2H), 0.92 (t, J=6.6 Hz, 3H).
