5625-67-2,With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.5625-67-2,Piperazin-2-one,as a common compound, the synthetic route is as follows.
To a stirred solution of W-l (20.0 g, 0.200 mol) in DCM, is added Boc anhydride (43.6 g, 0.200 mol), and TEA (40.4 g, 0.400 mol). The mixture is stirred at about 25 C for about 18 hours. The mixture is concentrated and the residue dissolved in EtOAc then extracted with water. The organic layer is concentrated and the residue is purified by silica gel chromatography to give W-2.
As the paragraph descriping shows that 5625-67-2 is playing an increasingly important role.
