실험 절차

A solution of tert-butyl (Z)-4-(4-{2-[(1H-indazol-3-yl)methylene]-6-methoxy-3-oxo-2,3-dihydrobenzofuran-7-yl}butyl)piperidine-1-carboxylate (0.0454 g, 0.0854 mmol) in methylene chloride (3 mL) was added with a 4 M solution of hydrogen chloride in 1,4-dioxane (3 mL), and the mixture was stirred at room temperature for 2 hours. The reaction mixture was concentrated, the resulting residue was added with saturated aqueous sodium hydrogencarbonate, and the mixture was extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulfate, and then the solvent was evaporated. The resulting solid was suspended in methylene chloride and thereby washed to obtain (Z)-2-[(1H-indazol-3-yl)methylene]-6-methoxy-7-[4-(piperidin-4-yl)butyl]benzofuran-3(2H)-one (0.0243 g, 66%).
