In the title compound, C22H18BrN5O4, the central six-membered ring, derived from 1,4-di-hydro-pyridine, adopts a distorted boat conformation with a puckering amplitude of 0.197 (3) Å, the imidazole ring adopts a twisted conformation with a puckering amplitude of 0.113 (3) Å, and the oxindole moiety is planar with an r.m.s. deviation of 0.0125 Å. Two intra-molecular N-H⋯O hydrogen bonds are formed, each closing an S(6) loop. In the crystal, strong N-H⋯O hydrogen bonds lead to the formation of zig ...[more]
