実験手順
Hydrazine hydrate (3.06 g) was added to a suspension of 3'-phthalimidomethyl-4'-methoxyacetophenone (15.74 g) in methanol (150 ml) and tetrahydrofuran (150 ml) at room temperature and the mixture was stirred at room temperature for 24 hours. Dilute hydrochloric acid (conc. hydrochloric acid (5 ml) in water (100 ml)) was added slowly to the mixture with cooling and the mixture was stirred at room temperature for 1 hour. The mixture was concentrated. Water (100 ml) was added thereto and the mixture was alkalized to pH 10 with 30% aqueous potassium carbonate solution and extracted with ethyl acetate (300 ml). The extract was dried with magnesium sulfate. The solvent was removed under reduced pressure to afford 3'-aminomethyl-4'-methoxyacetophenone (4.45 g).
