Procedure

A solution of 1 g (3,6 mol) of 6,8-dibromoimidazo[1,2-a]pyrazine and 1 g (11.2 mmol) of morpholine in 15 ml of anhydrous ethanol is brought to reflux for 12 hours. After evaporation of the solvant and chromatography on an alumina column (eluant=CH2Cl2), 0.88 g (Yld=85%) of 6-bromo 8-morpholinoimidazo[1,2-a]pyrazine (m.p. 191° C.) is obtained.
