Reaction Steps

To (S,E)-ethyl 6-((5-(5-(2-(4-(dimethylamino)-N-methyl-2-butenamido)propaneamido)-1-pentyn-1-yl)-4-(propylamino)pyrimidin-2-yl)amino)-1H-indazole-1-carboxylate (21-23, 17.3 mg), tetrahydrofuran (1.0 mL) and 1.0 mol/L aqueous lithium hydroxide (1.0 mL) were added at room temperature, and the mixture was stirred at the same temperature for 30 minutes. To the reaction mixture, water and ethyl acetate were added. The organic layer was separated, washed with saturated aqueous sodium chloride, and then dried over anhydrous sodium sulfate, and the solvent was evaporated under reduced pressure. The obtained residue was purified by basic silica gel column chromatography (eluent, 100 to 90% ethyl acetate in methanol) to obtain (S,E)-N-(1-((5-(2 -((1H-indazol-6-yl)amino)-4-(propylamino)pyrimidin-5-yl)-4-pentyn-1-yl)amino)-1-oxopropan-2-yl)-4-(dimethylamino)-N-methyl-2-butenamide (21-53, 9.8 mg) as pale yellow solid.
