The structure of the title compound, C(12)H(9)BrN(4), prepared by the reaction of 2-bromo-1-(6-bromo-3-pyrid-yl)ethanone with 2-amino-3-methyl-pyrazine indicates that the compound with the bromo-pyridyl 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, mol-ecules are linked by weak C-H⋯N inter-actions.
通过2-溴-1-(6-溴-3-吡啶基)乙酮与2-氨基-3-甲基吡嗪反应制备的标题化合物C(12)H(9)BrN(4)的结构表明,在咪唑并吡嗪稠环体系的2位带有溴代吡啶基取代基的化合物是该反应的主要产物。吡啶环平面与基本呈平面的(均方根偏差 = 0.006 Å)咪唑并吡嗪体系形成16.2 (2)°的二面角。在晶体中,分子通过弱C-H⋯N相互作用相连。
