Abstract
In the title compound, C23H17F3N2O3, an intramolecular C—H⋯F hydrogen bond generates an S(6) ring motif. The essentially planar 1H-benzimidazole ring system [maximum deviation = 0.021 (2) Å] forms dihedral angles of 25.00 (10) and 62.53 (11)° with the trifluoromethoxy-substituted benzene and phenyl rings, respectively. The twist of the ethyl acetate group from the least-squares plane of the 1H-benzimidazole ring system is defined by a C(=O)—O—C—C torsion angle of 79.5 (3)°. In the crystal, molecules are linked into a two-dimensional network parallel to the bc plane by weak C—H⋯N and C—H⋯O hydrogen bonds. Weak C—H⋯π interactions also observed.
