With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.67455-41-8,4-(Piperazin-1-yl)aniline,as a common compound, the synthetic route is as follows.
A mixture of 4-(piperazin-l-yl)aniline (348 mg, 1.968 mmol), (E)-methyl 3-(2-(2-chloropyrimidin-5-yl)vinyl)-5-methoxybenzoate (600 mg, 1.968 mmol) and TFA (672 mg, 5.904 mmol) in propan-2-ol (30 mL) was stirred at 150 C for 40 min under microwave. The resulting mixture was concentrated, basified with ammonia water, purified via ISCO (DCM/MeOH) to afford the title compound as a yellow solid (320 mg, 36.6% yield). MS (m/z): 446.3(M+H)+.
67455-41-8 4-(Piperazin-1-yl)aniline 422925, apiperazines compound, is more and more widely used in various.
