실험 절차

A solution of tert-butyl 4-((E)-2-{(Z)-2-[(1H-indazol-3-yl)methylene]-6-methoxy-3-oxo-2,3-dihydrobenzofuran-7-yl}vinyl)piperidine-1-carboxylate (0.0693 g, 0.138 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 washed with saturated brine, and dried over anhydrous sodium sulfate, and then the solvent was evaporated to obtain (Z)-2-[(1H-indazol-3-yl)methylene]-6-methoxy-7-[(E)-2-(piperidin-4-yl)vinyl]benzofuran-3(2H)-one (0.0473 g, 85%).
