Versuchsvorschrift

3-Pyrrolidinophenethyl alcohol was dissolved in dichloromethane (20 ml). Triethylamine (3.7 ml, 26.7 ml) and methanesulfonyl chloride (1.9 ml, 24.5 mmol) were added to the obtained solution at 0° C., and they were stirred overnight. The reaction mixture was distributed into 5% aqueous sodium hydrogencarbonate solution and dichloromethane. The organic layer was dried and the solvent was evaporated under reduced pressure. The residue was subjected to the silica gel column chromatography. After the elution with hexane and ethyl acetate (7:3), suitable fractions were collected and the solvent was evaporated under reduced pressure to obtain 3-pyrrolidinophenethyl mesylate in the form of a white solid (5.13 g, 87%).
