実験手順
A solution of 3-(2-methyl-1,3-dioxolan-2-yl)benzylamine (57.2 g) in 1N hydrochloric acid (500 ml) and methanol (500 ml) was stirred at room temperature for 2 hours. The solvent was removed under reduced pressure. The residue was dissolved in methanol. The resulting precipitate was removed by filtration. The solvent was removed under reduced pressure. Recrystallization from a mixture of ethanol and acetone afforded 3-acetylbenzylamine hydrochloride (31.2 g).
