A common heterocyclic compound, 63744-22-9, name is 6,8-Dibromoimidazo[1,2-a]pyrazine, molecular formula is C6H3Br2N3, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route. 63744-22-9.
General procedure: Method F: compound 6 (2 mmol) was dissolved in MeOH, and stirred at 0 C., to which was added NaSMe (20% aq, 1.8 eq.), followed by naturally warming to room temperature, and reacting overnight, monitored by TCL until complete conversion, to which was added DCM. The system was washed with water, and the organic phase was concentrated to obtain a while solid, which was directly used for the next step reaction.
The synthetic route of 6,8-Dibromoimidazo[1,2-a]pyrazine has been constantly updated, and we look forward to future research findings.
