Uses
(R)-tert-butyl pyrrolidin-3-ylmethylcarbamate is a useful reagent in the research discovery of ethyl 5,6-dihydropyrazolo[1,5-c]quinazoline-1-carboxylate, a catalytic inhibitor of DNA gyrase and a potential antibacterial agent.
Synthesis
General procedure: tert-butyl (R)-(1-benzylpyrrolidin-3-ylmethyl)carbamate (1.00 g, 3.44 mmol) was mixed with 20% Pd/C and subjected to hydrogenation under hydrogen pressure of 50 psi.After 48 h, the reaction mixture was filtered to remove the catalyst, and the filtrate was concentrated to give 511 mg of tert-butyl (3R)-pyrrolidin-3-methylcarbamate ( Yield: 74%). Mass spectrometry analysis (APCI+): m/z 201 ([M + H]+).
