Procedure

A mixture of 3-(aminomethyl)-4,6-dimethylpyridin-2(1H)-one (70 mg, 0.46 mmol), 5-methyl-1-phenyl-1H-pyrazole-4-carboxylic acid (93 mg, 0.46 mmol), O-(7-azabenzotriazole-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (210 mg, 0.55 mmol) and triethylamine (70 mg, 0.69 mmol) in anhydrous dichloromethane (5 mL) was stirred at room temperature for 15 hours. Then the mixture was filtered and the solid was washed with water (10 mL), methanol (10 mL) and dichloromethane (10 mL) in turns to give N-((4,6-dimethyl-2-oxo-1,2-dihydropyridin-3-yl)methyl)-5-methyl-1-phenyl-1H-pyrazole-4-carboxamide as a white solid (40 mg, 26%). LRMS (M+H+) m/z: calcd 336.16. found 336.
