Reaction Steps

To a stirred solution of 1-cyclopentyl-6-(1,2-dihydroxyethyl)-N-((4,6-dimethyl-2-oxo-1,2-dihydropyridin-3-yl)methyl)-1H-indazole-4-carboxamide (0.6 g, 1.4 mmol) in 50% THF/Water (16 mL), was added NaIO4 (0.9 g, 4.2 mmol) at 0° C. and stirred at room temperature for 1 h. After completion of reaction, solvent was removed under reduced pressure and water was added to it. Extraction was carried out using 10% MeOH/DCM. The combined organic layers were washed with water, dried over anhydrous Na2SO4, filtered and concentrated under reduced pressure to afford crude material which was purified by column chromatography to give 1-cyclopentyl-N-((4,6-dimethyl-2-oxo-1,2-dihydropyridin-3-yl)methyl)-6-formyl-1H-indazole-4-carboxamide (0.4 g, 72.1%).
