Reaction Steps

A solution of tert-butyl 4-[(6-methoxy-3-oxo-2,3-dihydrobenzofuran-7-yl)methyl]piperidine-1-carboxylate (0.0518 g, 0.143 mmol) in methanol (5 mL) was added with 1H-indazole-3-carboxaldehyde (0.0220 g, 0.151 mmol) and piperidine (0.100 mL, 1.01 mmol), and the mixture was stirred at 60° C. for 2 hours. The reaction mixture was concentrated, and the resulting residue was purified by silica gel column chromatography (chloroform/ethyl acetate) to obtain tert-butyl (Z)-4-({2-[(1H-indazol-3-yl)methylene]-6-methoxy-3-oxo-2,3-dihydrobenzofuran-7-yl}methyl)piperidine-1-carboxylate (0.0525 g, 75%).
