With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.13889-98-0,1-Acetylpiperazine,as a common compound, the synthetic route is as follows.
General procedure: A reaction vessel was charged with acetic acid (2.016 mmol) and TBHP (70% inwater, 1.008 mmol) in acetonitrile (2 mL). After the addition of [Bpy]I (0.1008 mmol),benzoxazole (0.672 mmol) and secondary amines (1.344 mmol) were added. Then thereaction mixture was stirred at room temperature for 3.5 hours. After the reactionfinished, the mixture was extracted with dichloromethane (5 × 10 mL), and thecombined organic phases were dried over anhydrous Na2SO4. The solvent wasevaporated under vacuo, and the crude residue was purified by columnchromatography on silica gel. Aqueous phase was dried in a vacuum evaporator torecover the ionic liquid and directly reused in subsequent runs., 13889-98-0
As the paragraph descriping shows that 13889-98-0 is playing an increasingly important role.
