Abstract

In the title mol-ecule, C(21)H(24)N(2)O(3), the imidazole ring is essentially planar, with a maxium deviation of 0.015 (1) Å. The dihedral angle between the benzene and imidazole rings is 65.47 (6)°. The crystal packing is stabilized by weak inter-molecular C-H⋯O and C-H⋯N hydrogen bonds, forming zigzag chains along the c axis. The crystal structure is further stabilized by C-H⋯π inter-actions.
