With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.59878-57-8,1-(Cyclopropylcarbonyl)piperazine,as a common compound, the synthetic route is as follows.
59878-57-8, To a stirred suspension of 4-(bromomethyl)-6-(trifluoromethyl)pyridin-2-amine hydrobromide (2.10 g, 6.25 mmol) in acetonitrile (13 mL) was added potassium carbonate and cyclopropyl(piperazin-1-yl)methanone (1.06 g, 6.88 mmol). The mixture was stirred atr.t. for 14 h. Water was added and the mixture was extracted with ethyl acetate. The organic phase waswashed with half-saturated sodium chloride solution, dried (sodium sulfate) and the solvent was removed in vacuum. Ssilicage chromatography gave 2.00 g (98 % yield) of the title compound.LC-MS (Method 2): R = 0.94 mm; MS (ESipos): m/z = 329 [M+H]
59878-57-8 1-(Cyclopropylcarbonyl)piperazine 2064235, apiperazines compound, is more and more widely used in various fields.
