実験手順

A solution of 2-amino-5-[4-((R)-2,2-dimethyl-[1,3]dioxolan-4-ylmethoxy)-phenyl]-pentanenitrile (1.7 g, 4.28 mmol) in a 2M ammonia in methanol solution (50 ml) is passed through a H-CUBE apparatus fitted with a Raney nickel CatCart at 50° C. and a hydrogen pressure of 50 bar and a flow rate of 1.5 ml/min. After 5 hours of continuous cycling of the solution the reaction mixture is concentrated in vacuo to give 5-[4-((R)-2,2-Dimethyl-[1,3]dioxolane-4-ylmethoxy)-phenyl]-pentane-1,2-diamine as a light-yellow oil; [M+H]+ 309
