実験手順

A solution of tert-butyl (Z)-4-({6-hydroxy-2-[(6-nitro-1H-indol-3-yl)methylene]-3-oxo-2,3-dihydrobenzofuran-7-yl}methyl)piperazine-1-carboxylate (0.020 g, 0.038 mmol) in methylene chloride (2.0 mL) was added with a 4 M solution of hydrogen chloride in 1,4-dioxane (2.0 mL), and then the mixture was stirred at room temperature for 2 hours. The mixture was azeotroped twice with toluene under reduced pressure, and then the residual solid was suspended in a mixed solvent of methylene chloride and diethyl ether and thereby washed to obtain (Z)-6-hydroxy-2-[(6-nitro-1H-indol-3-yl)methylene]-7-(piperazin-1-ylmethyl)benzofuran-3(2H)-one dihydrochloride (0.014 g, 75%).
