With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.692058-21-2,1-Boc-4-(2,2,2-trifluoroethyl)piperazine,as a common compound, the synthetic route is as follows.
[19121 Step 2: Synthesis of 1-(2.2.2-trifluoroethyl)piperazine[19131 Tert-butyl 4-(2,2,2-trifluoroethyl)piperzine- 1 -carboxylate (2.000 g, 7.455 mmol) was dissolved in methylene chloride (10 mL) / trifluoroacetic acid (5 mL) at room temperature, and the solution was stirred at the same temperature for 17 hours. The reaction mixture was concentrated under reduced pressure to remove the solvent, and the concentrate was crystallized from ethyl acetate (20 mL) at room temperature and filtered, and the resulting solid was washed with ethyl acetate and dried to afford the desired compound (0.457 g, 23.1 %) as a white solid.
692058-21-2, As the paragraph descriping shows that 692058-21-2 is playing an increasingly important role.
