Reaction Steps

A solution of tert-butyl (Z)-4-({2-[(1H-indazol-3-yl)methylene]-6-(benzyloxy)-3-oxo-2,3-dihydrobenzofuran-7-yl}methyl)piperazine-1-carboxylate (0.0720 g, 0.127 mmol) in methylene chloride (2 mL) was added with trifluoroacetic acid (2 mL) at room temperature, and the mixture was stirred overnight. The reaction mixture was added with water (6 mL) and saturated aqueous sodium hydrogencarbonate (6 mL), and thereby adjusted to pH 8, and then the mixture was stirred at room temperature for 1 hour. The reaction mixture was filtered, and then the resulting solid was washed with water to obtain the objective (Z)-2-[(1H-indazol-3-yl)methylene]-6-(benzyloxy)-7-(piperazin-1-ylmethyl)benzofuran-3(2H)-one (0.0490 g, 82%).
