실험 절차
Heat a solution of 3,4-dimethoxybenzylamine (16.7 g) and styrene oxide (12.0 g) in acetonitrile (250 mL) at reflux for 16 h. Concentrate to a residue and distill the residue, collecting the fraction distilling above 120° C. (0.5 mm). Recrystallize the solidified distillate from benzene/hexane to give N-(3,4-dimethoxybenzyl)-2-hydroxy-2-phenylethylamine (13.4 g), mp=93°-94° C.
