2-(6-Bromo-3-pyrid­yl)-8-methyl­imidazo[1,2-a]pyrazine

The structure of the title compound, C(12)H(9)BrN(4), prepared by the reaction of 2-bromo-1-(6-bromo-3-pyrid­yl)ethanone with 2-amino-3-methyl­pyrazine indicates that the compound with the bromo­pyridyl substituent at position 2 of the imidazopyrazine fused-ring system represents the major product of this reaction. The plane of the pyridine ring forms a dihedral angle of 16.2 (2)° with the essentially planar (r.m.s. deviation = 0.006 Å) imidazopyrazine system. In the crystal, mol­ecules are linked by weak C—H⋯N inter­actions.
