Reaction Steps

A solution of 0.8 g (2.9 mmol) of 6,8-dibromoimidazo[1,2-a]pyrazine and 1.2 g of N-bromosuccinimide in 40 ml of chloroform is brought to reflux for two hours. After being cooled, the organic solution is treated with aqueous Na2CO3 solution. The chloroform phase is collected and then evaporated. 1 g -(Yld=97%) of 3,6,8-tribromoimidazo[1,2-a]pyrazine (m.p. 161° C.) is obtained.
