Yield:140447-78-5 97%
Reaction Conditions:
with hydrogen;palladium 10% on activated carbon in methanol for 2 h;
Steps:
22.D 22D: tert-Butyl 2-(1-piperazinyl)ethylcarbamate
Hydrogen was passed through a degassed solution of benzyl 4-(2-(tert-butyloxycarbonylamino)ethyl)piperazine-1-carboxylate (2.60 g, 7.16 mmol) in methanol (50 ml) containing 10% palladium on carbon (500 mg) for 2 h. The reaction mixture was filtered through Celite and the filtrate was concentratedin vacuo to give a yellow gum identified as tert-butyl 2-(1-piperazinyl)ethylcarbamate (1.60 g, 97%).
