Procedure

A solution of ethyl 3-(benzyl(methyl)amino)propanoate (3 g, 13.56 mmol) in ethanol (67.8 mL) was added palladium, 10 wt. % on carbon (0.3 g, 0.282 mmol) and hydrogenated (double-walled balloon pressure) at room temperature for 3 h. The reaction mixture was filtered via a pad of Celite, and the filtrate was concentrated in vacuo to give ethyl 3-(methylamino)propanoate (1.12 g, 63.0% yield) as a light golden yellow oil.
