With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.208167-83-3,tert-Butyl 4-(2-chloroethyl)piperazine-1-carboxylate,as a common compound, the synthetic route is as follows.
General procedure: A mixture of compound 9 (200mg, 0.8mmol), sodium iodine (289mg, 1.93mmol) and substituted amines (1.61mmol) in methanol (30mL) was stirred at 40C for 5h. After the reaction was completed (monitored by TLC), the solution was concentrated under vacuum. Then the crude residue was purified by column chromatography (dichloromethane/methanol), affording pure product 10., 208167-83-3
208167-83-3 tert-Butyl 4-(2-chloroethyl)piperazine-1-carboxylate 22106269, apiperazines compound, is more and more widely used in various fields.
