Reaction Steps

6-Bromo-N-((4,6-dimethyl-2-oxo-1,2-dihydropyridin-3-yl)methyl)-1H-pyrazolo[3,4-b]pyridine-4-carboxamide (0.25 g, 0.66 mmol) was dissolved in DMF (3 mL) and K2CO3 (0.17 g, 0.79 mmol) and (1-bromoethyl)benzene (0.148 g, 0.799 mmol) was added to it. The reaction mixture was refluxed for overnight. On completion, water was added to it. Extraction was carried out using DCM; the combined organic layers were washed with water, brine and dried over anhydrous Na2SO4. Solvent was removed under reduced pressure and residue was purified by silica gel column chromatography to obtain the desired intermediate (0.26 g, 92.8%).
