Procedure

To a THF (3 ml) solution of (E)-1-{3-[3-methoxy-4-(4-methyl-1H-imidazol-1-yl)phenyl]acryloyl}-4-phenylpyrrolidine-3-carbaldehyde oxime (17.8 mg) obtained in Example 359, CDI (32.4 mg) was added at room temperature, and heat-refluxing was carried out for 3 hours. After the reaction solution was allowed to be cooled to room temperature, ethyl acetate and saturated sodium bicarbonate solution were added to the reaction solution, and the organic layer was partitioned. After drying the obtained organic layer with anhydrous magnesium sulfate, the solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography (elution solvent:ethyl acetate methanol 10:1), and the 14.6 mg (86%) title compound was obtained. The physical properties of the compound are as follows.
