Abstract
The title compound, C20H18N2O·CH3CN, a perimidine derivative, crystallized as an acetonitrile monosolvate. The planes of the naphthalene ring system and the methoxyphenyl ring are oriented almost perpendicular to one another, with a dihedral angle of 87.61 (6)°. The conformation about the C=C bond is E. The hexahydropyrimidine ring has an envelope conformation, with the methine C atom as the flap. In the crystal, the molecules are linked by N—H⋯N hydrogen bonds involving the acetonitrile solvent molecule as acceptor, forming zigzag chains propagating along [100].
