With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.112257-24-6,1-Boc-3-Carbamoylpiperazine,as a common compound, the synthetic route is as follows.
tert-Butyl 4-(1-benzhydrylazetidin-3-yl)-3-carbamoylpiperazine-1-carboxylate A mixture of 1-benzhydrylazetidin-3-yl methanesulfonate (2.69 g, 8.5 mmol), K2CO3 (1.76 g, 12.8 mmol), tert-butyl 3-carbamoylpiperazine-1-carboxylate (1.95 g, 8.5 mmol) in CH3CN (40 mL) was stirred at reflux for 16 h. The mixture was partitioned between ethyl acetate and water. The organic layer was washed with water and brine, dried over Na2SO4, and concentrated in vacuo. The residue was purified by flash column chromatography on silica gel (dichloromethane/methanol=50:1) to afford the desired product. (2.08 g, 54% yield).
112257-24-6, As the paragraph descriping shows that 112257-24-6 is playing an increasingly important role.
