Dichloromethane → 6-[2-[4-(2-Fluorophenoxymethyl)piperidino]ethyl]-1H-pyrazin-2-one

Participants

Reaction Steps

After dissolving 167 mg of 2-tert-butoxy-6-[2-[4-(2-fluorophenoxymethyl)piperidino]ethyl]pyrazine in 3 ml of ethyl acetate, 3 ml of 4N hydrogen chloride/ethyl acetate was added and the mixture was all owed to stand at room temperature for 30 minutes. Aqueous sodium carbonate solution was added to the reaction solution and extraction was performed with dichloromethane. The organic layer was washed with saturated brine and dried over anhydrous magnesium sulfate, and then 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 (113 mg, 79% yield).
