With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.115761-79-0,1-(2,4-Difluorophenyl)piperazine,as a common compound, the synthetic route is as follows.
General procedure: To a solution of 4 (100 mg, 0.23 mmol) in acetonitrile (CH3CN, 10 mL) was added the corresponding arylpiperazines (1.2 equiv) and potassium carbonate (6.0 equiv). The reaction mixture was stirred at reflux for 16 h. After cooling to ambient temperature, the reaction mixture was filtered through a Buchner funnel. After filtration the filtrate was concentrated in vacuo and the residue was purified by silica gel column chromatography using ethyl acetate/petroleum ether (1:4, v/v) as eluent to afford the corresponding products, and all compounds were recrystallized from trichloromethane and n-hexane., 115761-79-0
The synthetic route of 115761-79-0 has been constantly updated, and we look forward to future research findings.
