実験手順

A suspension of (S)-4-(2-azido-ethyl)-2,2-dimethyl-[1,3]dioxolane as a yellow oil (18.7 g, 0.11 mol) and PtO2 (2.5 g) in ethyl acetate (100 mL) was vigorously shaken in a Parr under atmosphere of H2 (50 psi) for 18 h. The mixture was filtered through a short pad of celite. The filtrate was concentrated to give 2-((S)-2,2-dimethyl-[1,3]dioxolan-4-yl)-ethylamine as a colorless oil (14 g, 88%).
