실험 절차

A solution of tert-butyl (Z)-4-(2-{2-[(1H-pyrazolo[3,4-b]pyridin-3-yl)methylene]-6-methoxy-3-oxo-2,3-dihydrobenzofuran-7-yl}ethyl)piperidine-1-carboxylate (0.0652 g, 0.129 mmol) in methylene chloride (5 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, and then added with saturated aqueous sodium hydrogencarbonate, and the precipitated solid was collected by filtration. The solid was washed with water, and then dried under reduced pressure to obtain (Z)-2-[(1H-pyrazolo[3,4-b]pyridin-3-yl)methylene]-6-methoxy-7-[2-(piperidin-4-yl)ethyl]benzofuran-3(2H)-one (0.0402 g, 77%).
