Participants

Reaction Steps

After adding 2 ml of 4N hydrogen chloride/ethyl acetate to the obtained 1-[1-(3-tert-butoxy-2-pyrazinylmethyl)piperidin-4-yl]-2-(2-methoxyphenyl)ethanone, the mixture was stirred overnight at room temperature. Aqueous 1N sodium hydroxide was added to the reaction solution for adjustment to pH 8, and extraction was performed with dichloromethane. The organic layer was washed with saturated brine and dried over anhydrous magnesium sulfate, and the solvent was distilled off under reduced pressure. Diethyl ether was added and the precipitate was filtered out to obtain the title compound (89 mg, 34% yield, 3 steps).
