Reaction Conditions

Reaction Steps

In a four-aperture flask, 9.6 g (70 mmol) of p-aminophenethyl alcohol, 38.7 g (280 mmol) of potassium carbonate, and 100 mL of monochlorobenzene were poured, and the mixture was heated at 120° C. under an argon atmosphere with stirring. Then, 32.8 g (210 mmol) of ethyl iodide was delivered by drops into the mixture for 5 hours. Upon completion of the dripping, the mixture was further heated with stirring for 5 hours. The reaction solution was cooled to the room temperature and then diluted with dichloromethane, followed by washing with water three times. The dichloromethane solution was dried with anhydrous magnesium sulfate, the solvent was distilled away to purify the dichloromethane solution by silica gel chromatography using a mixture solvent of toluene/ethyl acetate (2/1) as an eluent to thereby synthesize 12.1 g (yield: 89% by mass) of p-diethylaminophenethyl alcohol.
