With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.59878-57-8,1-(Cyclopropylcarbonyl)piperazine,as a common compound, the synthetic route is as follows.
A mixture of 6-bromopyrrolo[1,2-b]pyridazin-4-yl trifluoromethanesulfonate (30 g, 86.9 mmol), cyclopropyl(piperazin-1-yl)methanone (16.0 g, 104 mmol), and triethylamine (13.1 g, 130 mmol) in NMP (300 mL) was stirred at 100 C for 30 mm. The reaction mixture was cooled and diluted with EA. The organic layer was washed with water and brine, concentrated andpurified by silica gel column to give the title product (26.0 g, yield 86%) as a yellow solid. MS (ES+) C15H17BrN4O requires: 348, found: 349 [M+H]., 59878-57-8
The synthetic route of 59878-57-8 has been constantly updated, and we look forward to future research findings.
