Versuchsvorschrift

12.5 ml of 4N-HCl/dioxane solution were added to 0.66 g (2.5 mmols) of N-t-butoxycarbonyl-(R)-α-ethoxymethylbenzylamine, and the mixture was stirred at room temperature for one hour. The reaction mixture was concentrated under reduced pressure, 30 ml of ether was added to the residue, and this was further concentrated to obtain (R)-α-ethoxymethylbenzylamine hydrochloride at a quantitative yield.
