With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.55121-99-8,(4-Aminophenyl)(4-methylpiperazin-1-yl)methanone,as a common compound, the synthetic route is as follows.
General procedure: To a solution of9(0.16g,0.58mmol) ini-PrOH(5mL),substituted phenylamine(0.64mmol)wasadded. The reaction mixture was stirred at reflux for4h under N2atmosphere. After the reaction was completed, the mixture wasnaturally cooled to room temperature.Themixture was filtered and the solid was collectedto giveintermediate12or15. 1.2.1 (4-((6-Bromoquinazolin-4-yl)amino)phenyl)(4-methylpiperazin-1-yl)methanone (12a)Yellow solid; yield:73 %.MS (ESI)m/z: [M+H]+=426.1/428.1.
55121-99-8, The synthetic route of 55121-99-8 has been constantly updated, and we look forward to future research findings.
