실험 절차

A solution of 3.20 g (20.0 m mol) of tryptamine and 3.10 g (20.0 m mol) of phthalic anhydride in 40 ml of toluene was refluxed under a Dean-Stark water separator for 12 h. Cooling, filtration and concentration of the filtrate gave a crude phthalimide which was recrystallized from ethanol to produce 4.85 g (84%), of phthalimide, mp 164°-165° C.; reported 164°-165° C.3
