Ethyl 2-(4-meth­oxy­phen­yl)-1-3-(2-oxopyrrolidin-1-yl)prop­yl-1H-benzimidazole-5-carboxyl­ate

摘要

The asymmetric unit of the title compound, C24H27N3O4, contains two mol­ecules, A and B. The benzimidazole rings are essentially planar [maximum deviations = 0.0144 (10) and 0.0311 (8) Å in A and B, respectively]. The dihedral angle between the benzimidazole mean plane and its attached benzene ring is 36.90 (5) ° for mol­ecule A and 51.40 (5) ° for mol­ecule B. In both mol­ecules, the pyrrolidine ring adopts an envelope conformation with a C atom as the flap. In molecule B, the flap C atom is disordered over two positions in a 0.711 (6):0.289 (6) ratio. In the crystal, C—H⋯O inter­actions link the mol­ecules, generating [100] chains. The crystal packing also features weak π–π inter­actions between the imidazole and benzene rings [centroid–centroid distances = 3.8007 (7) and 3.8086 (7) Å] and between the benzene rings [centroid–centroid distance = 3.7001 (7) Å] and C—H⋯π inter­actions involving the benzene rings.
