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.
EXAMPLE 2 2-[4-(2,4-Difluorophenyl)piperazin-1-yl]ethanol Formula IX: n=2, STR13 A solution of 72 g of 4-(2,4-difluorophenyl)piperazine and 50 g of 2-bromoethanol in 300 ml of xylene containing 55 ml of triethylamine is heated under reflux for 6 hours. The solution is then cooled and ether is added. The precipitate of triethylamine hydrobromide formed is filtered off and the filtrate is concentrated in vacuo. The residue obtained is then crystallized from an isopropyl ether/pentane mixture. The crystals are filtered off, washed with the same mixture and then dried. 60 g of 2-[4-(2,4-difluorophenyl)piperazin-1-yl]ethanol are thus recovered in the form of crystals melting at 54 C., 115761-79-0
115761-79-0 1-(2,4-Difluorophenyl)piperazine 2734637, apiperazines compound, is more and more widely used in various fields.
