Reaction Steps

To a stirred solution of 1-cyclopentyl-N-((4,6-dimethyl-2-oxo-1,2-dihydropyridin-3-yl)methyl)-6-vinyl-1H-indazole-4-carboxamide (0.9 g, 2.3 mmol) in DCM (10 mL), was added N-methylmorpholine-N-oxide (0.81 g, 6.92 mmol) at 0° C. OsO4 (0.147 g, 0.576 mmol, 2.5% solution in t-BuOH) was then added. The resulting solution was stirred at room temperature for 1 h. After completion of reaction, water was added and extraction 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 title compound 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, 61.3%).
