Procedure

Lithium hydroxide (0.0668 g) was added to a mixed solution of 3-methoxy-4-(4-methyl-1H-imidazol-1-yl)benzaldehyde (0.20 g) and diethyl [(3S,9aS)-3-(3,4-difluorophenyl)-5-oxooctahydropyrrolo[1,2-a]azepin-6-yl]phosphonate obtained above (0.52 g) in tetrahydrofuran (1 mL)-ethanol (4 mL), and the reaction solution was stirred at room temperature for 12 hours. The reaction solution was added to ice-sodium bicarbonate water, followed by extraction with ethyl acetate. The extract was washed with brine, dried over anhydrous magnesium sulfate, and then concentrated under reduced pressure. The residue was purified by silica gel column chromatography (heptane-ethyl acetate system) to obtain 0.223 g of the title compound. The property values of the compound are as follows.
