Procedure

After dissolving 274 mg of 1-[2-(6-tert-butoxypyrazin-2-yl)ethyl]-4-(2-fluorophenoxymethyl)piperidin-4-ol in 3 ml of ethyl acetate, 3 ml of 4N hydrogen chloride/ethyl acetate was added and the mixture was allowed to stand at room temperature for 2 hours. Aqueous sodium bicarbonate solution was added to the reaction solution and extraction was performed with dichloromethane. After drying over anhydrous magnesium sulfate, the solvent was distilled off under reduced pressure. Diethyl ether was added to the residue and the mixture was filtered to obtain the title compound (186 mg, 79% yield).
