With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.5308-25-8,1-Ethylpiperazine,as a common compound, the synthetic route is as follows.
0.36 g of N-[4-tert-butyl-5-(4-chlorobenzyl)thiazol-2-yl]-2-chloroacetamide and 5 mL of tetrahydrofuran, Stir at room temperature, 0.24 g of pyridine and 0.23 g of N-ethylpiperazine are added; Reaction overnight, Desolvent, Add dichloromethane, Saturated salt water wash, Drying with anhydrous sodium sulfate, Desolvent, Add petroleum ether to precipitate solids, Suction filtration Wash with petroleum ether, Dry to give a pale yellow solid of N-[4-tert-butyl-5-(4-chlorobenzyl)thiazol-2-yl]-2-(4-ethylpiperazinyl)acetamide, Yield 71.3%, 5308-25-8
As the paragraph descriping shows that 5308-25-8 is playing an increasingly important role.
