PROCEDURE

实验过程

A solution of tert-butyl 4-[4-(6-methoxy-3-oxo-2,3-dihydrobenzofuran-7-yl)but-3-ynyl]piperidine-1-carboxylate (0.0500 g, 0.125 mmol) in methanol (5 mL) was added with 1H-indazole-3-carboxaldehyde (0.0166 g, 0.114 mmol) and piperidine (7 drops), 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-(4-{2-[(1H-indazol-3-yl)methylene]-6-methoxy-3-oxo-2,3-dihydrobenzofuran-7-yl}but-3-ynyl)piperidine-1-carboxylate (0.0507 g, 84%).
