実験手順
N-cinnamyl phthalimide (3 mmol) was mixed with 65% hydrazine hydrate (6 mmol, 2 equiv) and MeOH (10 ml), and the mixture was heated at 70° C. for 2 h. After the solvent was removed by a rotary evaporator, the solid residue was treated with 1N NaOH (30 ml), and the resulting mixture was extracted with EtOAc (4×50 ml) and dried. Evaporation of the solvent under reduced pressure afforded the crude product, which was purified by flash silica gel column chromatography (eluting with 5-20% MeOH in DCM) to give cinnamyl amine.
