Participants

Reaction Steps

To a solution of 294 mg (0.377 mmol) of 4-(4,4-Difluorocyclohexyl)-3-{fluoro[4-(trifluoromethyl)phenyl]methyl}-2-[1-(5-formylpyrimidin-2-yl)piperidin-4-yl]-5-[(4-methoxybenzyl)oxy]-7,7-dimethyl-5,6,7,8-tetrahydroquinoline, which was prepared by a method similar to that of Reference Example 16, in 5 ml of tetrahydrofuran, 0.5 ml (0.5 mmol) of 1.0 mol/L isobutylmagnesium bromide-tetrahydrofuran solution was added under an argon gas atmosphere, and the reaction solution was stirred at room temperature for 0.17 hour. Then, 1.0 ml (1.0 mmol) of 1.0 mol/L isobutylmagnesium bromide-tetrahydrofuran solution was further added thereto and the reaction solution was stirred at room temperature for 0.33 hour. After completion of the reaction, the reaction solution was poured into saturated ammonium chloride aqueous solution and extracted with ethyl acetate. The organic layer was washed with saturated sodium chloride aqueous solution and then the solvent was distilled off under reduced pressure to provide 328 mg of the title compound as a foam (yield: quantitative).
