Procedure
A mixture of 4-benzoylbenzoic acid (106 mg, 0.5 mmol), o-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethylluroniumhexafluorophosphate (285 mg, 0.75 mmol), triethylamine (152 mg, 1.5 mmol) and dichloromethane (15 mL) were stirred at 25° C. for half an hour. Then 3-(aminomethyl)-4,6-dimethylpyridin-2-ol (76 mg, 0.5 mmol) was added. The mixture was stirred at 25° C. for 12 hours. The resultant mixture was washed with water (20 mL). The organic phase was separated, 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 4-benzyl-N-((2-hydroxy-4,6-dimethylpyridin-3-yl)methyl)benzamide as a white solid (50 mg, 29%). LRMS (M+H+) m/z: 346.17. found 346. HPLC purity (214 nm): 97%. 1H NMR (300 MHz, d6-DMSO): δ 11.50 (s, 1H), 8.29 (t, J=4.8 Hz, 1H), 7.76 (d, J=8.4 Hz, 2H), 7.28-7.13 (m, 7H), 5.85 (s, 1H), 4.30 (d, J=4.8 Hz, 2H), 3.96 (s, 2H), 2.16 (s, 3H), 2.11 (s, 3H).
