Procedure

1.4 g (0.005 mol) of tert-butyl 4-(2-carbamoylmethoxyethyl)piperazine-1-carboxylate prepared in Example I.4.1. and 14 ml of a 3M solution of hydrochloric acid in ethyl acetate are introduced into a 50 ml three-necked round-bottomed flask fitted with a water-cooled condenser and a mechanical stirrer. The mixture is stirred at room temperature for 2 hours. The precipitate is filtered off and is washed with ethyl acetate. 1.3 g (100%) of 2-(1-piperazinyl)ethoxyacetamide dihydrochloride are obtained.
