With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.103-76-4,N-(2-Hydroxyethyl)piperazine,as a common compound, the synthetic route is as follows.
103-76-4, [00212] Step 1 : To a solution of 4-fluoronitrobenzene (2.0g, 14.16 mmol) in AcN (15 mL), 2-(piperazin-l-yl)ethanol (1.85 g, 14.17mmol) and DIEA (2.97 mL, 17.01 mmol) were added. The mixture was refluxed for 15 h (in a sealed tube). After cooling, the resulting mixture was poured to water (300 ml). The mixture was stirred at room temperature for 30 min. The solids were collected by filtration and washed with water to afford the the desired product as off white solids (2.74g, 72% yield). ESI-MS calcd for (C12H17N303) 251, found 252 [M+H]+.
103-76-4 N-(2-Hydroxyethyl)piperazine 7677, apiperazines compound, is more and more widely used in various fields.
