実験手順

A solution of tert-butyl (Z)-4-(3-{2-[(1H-indazol-3-yl)methylene]-6-methoxy-3-oxo-2,3-dihydrobenzofuran-7-yl}propyl)piperidine-1-carboxylate (0.0313 g, 0.0605 mmol) in methylene chloride (2 mL) was added with a 4 M solution of hydrogen chloride in 1,4-dioxane (2 mL), and the mixture was stirred at room temperature for 2 hours. The reaction mixture was added with ether, and the precipitated solid was collected by filtration, and washed with ether. The resulting solid was dissolved in a small volume of water, and the solution was adjusted to pH 9 with saturated aqueous sodium hydrogencarbonate. The solution was extracted with ethyl acetate, the organic layer was dried over anhydrous sodium sulfate, and then the solvent was evaporated to obtain (Z)-2-[(1H-indazol-3-yl)methylene]-6-methoxy-7-[3-(piperidin-4-yl)propyl]benzofuran-3(2H)-one (0.0223 g, 88%).
