Reaction Steps

A solution of tert-butyl 4-[1-(6-hydroxy-3-oxo-2,3-dihydrobenzofuran-7-yl)methyl]piperazine-1-carboxylate (0.103 g, 0.295 mmol) in methanol (1.2 mL) was added with 5-(trifluoromethoxy)-1H-indazole-3-carbaldehyde (0.0680 g, 0.295 mmol), and piperidine (0.00251 g, 0.0295 mmol) at room temperature, and the mixture was stirred at 60° C. for 3 hours. The solvent was evaporated, and then the residue was purified by silica gel column chromatography (chloroform/methanol) to obtain tert-butyl (Z)-4-[(6-hydroxy-3-oxo-2-{[5-(trifluoromethoxy)-1H-indazol-3-yl]methylene}-2,3-dihydrobenzofuran-7-yl)methyl]piperazine-1-carboxylate (0.0660 g, 40%).
