Versuchsvorschrift

3 M methylmagnesium bromide-diethyl ether solution (0.84 mL) was added to a solution of 1-(5-methyl-2-(pyridin-4-yl)benzoyl)piperidin-4-one (0.37 g) in THF (10 mL) at 0° C., and the mixture was stirred overnight at room temperature. To the reaction mixture was added water at 0° C., and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (NH, ethyl acetate/hexane) to give the title compound (0.19 g).
