実験手順

A mixture of ethyl 3-(N-benzyloxycarbonyl-N-methylamino)propionate (8 g), 10% palladium on carbon (1.6 g, 50% wet), conc.-hydrochloric acid (5.1 ml) in methanol (160 ml) was stirred for 5 hours at room+temperature under hydrogen atmosphere. Catalyst was removed by filtration and mother liquor was concentrated in reduced pressure to give ethyl 3-(methylamino)propionate hydrochloride (4.31 g).
