With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.883554-88-9,4-Carbamoyl-piperazine-1-carboxylic acid tert-butyl ester,as a common compound, the synthetic route is as follows.,883554-88-9
To a solution of tert-butyl4-carbamoylpiperazine-1-carboxylate (0.16 g, 0.7 mmol) in DCM (2 mL) was addeda HCl in EtOAc solution (4 M, 2 mL) . The mixture was stirred at rt for 30 min andconcentrated to give the title compound as a white solid (0.16 g, 100) . 1H NMR (600 MHz, CD3OD): delta ppm 3.71-3.73 (m, 4H) , 3.25-3.27 (m, 4H) and MS-ESI: m/z 130.10[M+H-HCl] + .
883554-88-9 4-Carbamoyl-piperazine-1-carboxylic acid tert-butyl ester 17750351, apiperazines compound, is more and more widely used in various fields.
