Introduction of a new synthetic route about 6,8-Dibromoimidazo[1,2-a]pyrazine

In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 6,8-Dibromoimidazo[1,2-a]pyrazine, other downstream synthetic routes, hurry up and to see.

Adding a certain compound to certain chemical reactions, such as: 63744-22-9, name is 6,8-Dibromoimidazo[1,2-a]pyrazine, belongs to Pyrazines compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 63744-22-9, 63744-22-9

[0276] 6-Bromo-N-(4-(4-(oxetan-3-yI)piperazin-1-yl)phenyl)imidazo[1,2- a]pyrazm-8-amine III: To 4-(4-(oxetan-3-yl)piperazin-1-yl)aniline II (2.00 g, 8.57 mmoles), hunig’s base (3.29 mL) and 6,8-dibromoimidazo[ 1,2-a]pyrazine (2.37 g, 8.57 mmoles) was added in DMF (43 mL). The reaction was stirred at 85 C in a pressure tube for overnight. The material was quenched with saturated sodium bicarbonate, extracted with DCM (120 mL x 3) and the organic layers were combined and washed with water (120 mL x 3), dried over anhydrous sodium carbonate and concentrated. The crude material was purified using a 120 g Isco column and eluted off using a stepwise gradient of 0-60% (10% MeOH/DCM). The desired fractions were combined and concentrated to provide the title compound PiIota as a light yellow solid (3.00 g, 6.99 mmoles, 82%).

In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 6,8-Dibromoimidazo[1,2-a]pyrazine, other downstream synthetic routes, hurry up and to see.
