실험 절차

To a stirred solution of 6-bromo-N-((4,6-dimethyl-2-oxo-1,2-dihydropyridin-3-yl)methyl)-1H-pyrazolo[3,4-b]pyridine-4-carboxamide (0.4 g, 1.0 mmol) in DMF (4 mL), K2CO3 (0.152 g, 1.10 mmol) and 3 chloro-2-methylpropene (0.115 g, 1.27 mmol) were added. Resulting reaction mixture was stirred at 80° C. for 2 h. On completion of reaction, water was added to it and extraction was carried out using 20% MeOH/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 (0.2 g, 43.8%).
