Procedure

A solution of tert-butyl 4-[(6-hydroxy-3-oxo-2,3-dihydrobenzofuran-7-yl)methyl]piperazine-1-carboxylate (0.100 g, 0.287 mmol) obtained in Example A16, Step 1 in methanol (1.2 mL) was added with 1-(2,6-dichlorophenylsulfonyl)-1H-indole-3-carboxaldehyde (0.0918 g, 0.287 mmol) and piperidine (0.00244 g, 0.0287 mmol), and the mixture was stirred overnight at room temperature. The reaction mixture was added with methanol (2 mL), and the solid was suspended in methanol and thereby washed to obtain tert-butyl (Z)-4-[(2-{[1-(2,6-dichlorophenylsulfonyl)-1H-indol-3-yl]methylene}-6-hydroxy-3-oxo-2,3-dihydrobenzofuran-7-yl)methyl]piperazine-1-carboxylate (0.137 g, 69%).
