Abstract

In the title compound, C20H21BrN2O2, the bromophenyl ring is twisted by 40.13 (8)° from the benzimidazole mean plane and the Br atom deviates by 0.753 (1) Å from that plane. The sec-butyl group is disordered over two conformations in a 0.898 (5):0.102 (5) ratio. In the crystal, molecules related by translation along [10] are linked into chains via weak C—H⋯Br hydrogen bonds.
