実験手順

To a stirred solution of 1-cyclopentyl-N-((4,6-dimethyl-2-oxo-1,2-dihydropyridin-3-yl)methyl)-6-(4-formyl-2-methylphenyl)-1H-indazole-4-carboxamide (0.15 g, 0.31 mmol) in methanol (5 mL), morpholine (0.081 g, 0.93 mmol) and acetic acid (0.01 g, 0.311 mmol) were added at room temperature and reaction stirred at room temperature for 18 h. Then NaBH3CN (0.023 g, 0.37 mmol) was added and reaction stirred again at room temperature for 18 h. On completion, methanol was removed under reduced pressure and water added to the residue. The aqueous phase was extracted with 10% MeOH/DCM and the combined organic layers dried over sodium sulfate and concentrated to obtain crude material which was purified by column chromatography to afford 1-cyclopentyl-N-((4,6-dimethyl-2-oxo-1,2-dihydropyridin-3-yl)methyl)-6-(2-methyl-4-(morpholinomethyl)phenyl)-1H-indazole-4-carboxamide (34% yield).
