30459-17-7, 1-(4-Trifluoromethylphenyl)piperazine is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

A solution of methyl 3-bromo-2-phenylquinoxaline-6-carboxylate (150 mg, 0.44 mmol, 1.00 equiv) in DMF (8 rriL), l-(4-(trifluoromethyl)phenyl)piperazine (202 mg, 0.88 mmol, 2.00 equiv), DIEA (170.3 mg, 1.32 mmol, 3.00 equiv) were placed in a 20-mL sealed tube and stirred overnight at 100C in an oil bath. The reaction was then quenched by the addition of water. The resulting solution was extracted with 4×50 rriL of ethyl acetate and the organic layers combined and dried over anhydrous sodium sulfate followed by filtration to remove solids. The resulting mixture was concentrated under vacuum, resulting in 177.4 mg (78%) of methyl 2- phenyl-3-(4-(4-(trifluoromethyl)phenyl)piperazin-l-yl)quinoxaline-6-carboxylate as a yellow solid.LC-MS (ES, m/z): 492 [M+H]+

30459-17-7, 30459-17-7 1-(4-Trifluoromethylphenyl)piperazine 121718, apiperazines compound, is more and more widely used in various fields.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.30459-17-7,1-(4-Trifluoromethylphenyl)piperazine,as a common compound, the synthetic route is as follows.

General procedure: Carbonyldiimidazole (0.97g, 0.006mol) in 5mL of dry THF was added to a solution of intermediates 1 (1.11g, 0.006mol), 2 (1.19g, 0.006mol), 3 (1.19g, 0.006mol) or 4 (1.28g, 0.006mol) dissolved in 10mL of anhydrous THF while stirring. After the end of gaseous (carbon dioxide) evolution (c.a. 0.5h), the respective secondary amines (0.006mol) dissolved in 5mL of anhydrous THF was added dropwise. The mixture was stirred at room temperature (approx. 24h) and evaporated to dryness. The crude product was purified by column chromatography (dichloromethane/methanol, 9:0.3, v/v). The final amides were obtained as solid substances followed by concentration of organic solvents under reduced pressure, and recrystallization from 2-propanol.

30459-17-7, As the paragraph descriping shows that 30459-17-7 is playing an increasingly important role.
