Procedure

The mixture of 2-methyl-1-(1-phenylethyl)-1H-pyrrolo[3,2-b]pyridine-3-carboxylic acid (20 mg, 0.11 mmol), 2-(1H-7-Azabenzotriazol-1-yl)-1,1,3,3-tetramethyl uronium hexafluorophosphate Methanaminium (50 mg, 0.13 mmol), 3-(aminomethyl)-4,6-dimethylpyridin-2-ol (19 mg, 0.12 mmol) and triethylamine (23 mg, 0.22 mmol) in N,N-dimethylformamide (5 mL) was stirred for 12 hours. After the reaction was completed, the reaction was diluted with ethyl acetate (100 mL), and washed with water (20 mL×3) and brine (20 mL), dried over anhydrous sodium sulfate and concentrated to give the residue, which was purified by column chromatography (silica gel, dichloromethane/methanol=30:1) to give N-((2-hydroxy-4,6-dimethylpyridin-3-yl)methyl)-2-methyl-1-(1-phenylethyl)-1H-pyrrolo[3,2-b]pyridine-3-carboxamide (15 mg, 33%).
