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.
To a solution of 4,6-dichloro-2-methylpyrimidine (3.00 g) in dichloromethane (35 mL) was added 2-(piperazin-1-yl)ethanol (4.51 mL) at room temperature, and the mixture was stirred for 4 hr. To the reaction mixture was added triethylamine (0.513 mL) at room temperature, and the reaction mixture was stirred overnight. The resulting solid was collected by filtration, washed with dichloromethane, and dried under reduced pressure to give the title compound (4.08 g). 1H NMR (400 MHz, CDCl3) delta 2.48 (3H, s), 2.55-2.63 (6H, m), 3.63-3.73 (6H, m), 6.34 (1H, s)
103-76-4, 103-76-4 N-(2-Hydroxyethyl)piperazine 7677, apiperazines compound, is more and more widely used in various fields.
