2-(4-Bromophenyl)-N-[3-(1H-imidazol-1-yl)propyl]quinazolin-4-amine

Abstract

In the title compound, C20H18BrN5, the bromophenyl-substituted quinazoline unit is essentially planar [maximum deviation = 0.098 (3) Å] and makes a dihedral angle of 56.04 (14)° with the imidazole ring. In the crystal, molecules are associated by pairs of N—H...N hydrogen bonds to form inversion dimers. All the quinazoline planar systems are oriented almost perpendicular to the [110] direction, making π–π interactions possible between adjacent dimers [centroid–centroid distances = 3.7674 (16) and 3.7612 (17) Å]. There are also a number of C—H...π interactions present. The crystal is a nonmerohedral twin, with a minor twin fraction of 0.47.
