X.-F. Shi, H.-M. Liu and W.-Q. Zhang

Abstract: The title compound, C₁₂H₁₀N₂, belonging to the orthorhombic system with space group Pbca, was prepared by the condensation reaction of benzaldehyde and 2-methylpyrazine in DMF, using KOH as catalyst. The molecule is nearly planar, with a dihedral angle of 7.1 (3)° between the pyrazine and phenyl planes. In the crystal structure, molecules are connected by C-HN hydrogen bonds and weak - interactions, resulting in a two-dimensional network.
