With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.13889-98-0,1-Acetylpiperazine,as a common compound, the synthetic route is as follows.
2-[(4-Bromo-2-fluoro-phenyl)methyl]-6-phenyl-thiazinane 1,1-dioxide (208 mg, 0.52 mmol), Pd(OAc)2 (5.8 mg, 0.026 mmol), 2-dicyclohexylphosphine-2?,6?-di-iso-propoxy-1,1?-biphenyl (24.8 mg, 0.052 mmol) and cesium carbonate (254 mg, 0.78 mmol) were weighed out in a vial and the vial was purged with nitrogen. 1,4-Dioxane (2.5 mL) and 1-piperazin-1-ylethanone (100 mg, 0.78 mmol) were then added and the reaction was stirred at 80 C. for 2 hours. The reaction was then filtered through diatomaceous earth, concentrated and purified by reverse-phase HPLC to give 1-(4-(4-((1,1-dioxido-6-phenyl-1,2-thiazinan-2-yl)methyl)-3-fluorophenyl)piperazin-1-yl)ethanone (210 mg, 89% yield)., 13889-98-0
The synthetic route of 13889-98-0 has been constantly updated, and we look forward to future research findings.
