Procedure

To a solution of 6-bromo-N-((4,6-dimethyl-2-oxo-1,2-dihydropyridin-3-yl)methyl)-1-isopropyl-1H-pyrazolo[3,4-b]pyridine-4-carboxamide (1 equiv.) in DMSO (3 mL for 1 mmol), PyBOP (1.5 equiv.) was added and reaction stirred at room temperature for 15 min. Then 3-(aminomethyl)-4-ethyl-6-methylpyridin-2(1H)-one (2 equiv.) was added and reaction stirred overnight. On completion, water was added and solid that precipitates out was filtered and washed with water. Then this solid was stirred with acetonitrile for 10 min and filtered again to obtain the desired intermediate.
