Reaction Steps

After dissolving 237 mg of 2-tert-butoxy-3-[4-(2-chlorophenoxymethyl)-4-methylpiperidino]methyl-pyrazine in 3 ml of ethyl acetate, 3 ml of 4N hydrogen chloride/ethyl acetate was added while stirring on ice. After 1 hour, aqueous sodium carbonate solution was added to the reaction solution and extraction was performed with ethyl acetate. The organic layer was washed with water and 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 precipitate was filtered out to obtain the title compound (104 mg, 51% yield).
