1-(2-N-Boc-Aminoethyl)piperazine Chemical Properties,Usage,Production

Uses

1-[2-(Boc-amino)ethyl]piperazine is used in preparation of dihydropyrimidine derivatives as bifunctional degraders for treatment and prophylaxis of target protein-mediated diseases.

Synthesis

500013-42-3

140447-78-5

The general procedure for the synthesis of 1-(N-Boc-aminoethyl)piperazine from 1-CBZ-4-(BOC-aminoethyl)piperazine was as follows: hydrogen was vented into a degassed solution of benzyl 4-(2-(tert-butoxycarbonylamino)ethyl)piperazine-1-carboxylate (2.60 g, 7.16 mmol) containing 10% palladium carbon (500 mg) in methanol (50 ml), the reaction lasted for 2 hours. After completion of the reaction, the mixture was filtered through Celite. The filtrate was concentrated under vacuum to give a yellow colloidal product which was identified as tert-butyl 2-(1-piperazinyl)ethylcarbamate (1.60 g, 97% yield).
