With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.4318-42-7,1-Isopropylpiperazine,as a common compound, the synthetic route is as follows.,4318-42-7
Step D. [2-(3,4-Dichloro-phenoxy)-5-(4-isopropyl-piperazine-1- carbonvD-benzvH-methyl-carbamic acid tert-butyl ester.; To a solution of [5- bromo-2-(3,4-dichloro-phenoxy)-benzyl]-carbamic acid tert-butyl ester (327.0 mg, 0.71 mmol) in THF (2 ml.) were added DBU (0.30 ml_, 2.0 mmol), 1- isopropyl piperazine (0.30 ml_, 2.5 mmol), Hermann’s catalyst (31 .9 mg, 0.034 mmol), tri-f-butylphosphium tetrafluoroborate (26.4 mg, 0.091 mmol), and Mo(CO)6 (21 1.0 mg, 0.80 mmol). After 6 min in a microwave reactor at 125 0C, the mixture was cooled to rt and concentrated. Purification by FCC gave the desired product (212.5 mg, 56percent).
The synthetic route of 4318-42-7 has been constantly updated, and we look forward to future research findings.
