실험 절차

A solution of tert-butyl 4-[(6-methoxy-3-oxo-2,3-dihydrobenzofuran-7-yl)methyl]piperazine-1-carboxylate (0.488 g, 1.35 mmol) obtained in Example A40, Step 1 in methanol (5 mL) was added with 1-tosyl-1H-indole-3-carboxaldehyde (0.404 g, 1.35 mmol) obtained in Example A33, Step 1 and piperidine (0.0115 g, 0.135 mmol), and the mixture was stirred at 60° C. for 2 hours. The reaction mixture was cooled to room temperature, and then added with methanol (2 mL), and the precipitated solid was suspended in methanol and thereby washed. The reaction mixture was filtered to obtain tert-butyl (Z)-4-({6-methoxy-3-oxo-2-[(1-tosyl-1H-indol-3-yl)methylene]-2,3-dihydrobenzofuran-7-yl}methyl)piperazine-1-carboxylate (0.485 g, 55%).
