title: tert-Butyl 6-bromo-1,4-dimethyl-9H-carbazole-9-carboxyl-ate.
abstract: The title compound, C(19)H(20)BrNO(2), consists of a carbazole skeleton with methyl groups at positions 1 and 4, a protecting group located at the N atom and a Br atom at position 6. The pyrrole ring is oriented at dihedral angles of 1.27 (7) and 4.86 (7)° with respect to the adjacent benzene rings. The dihedral angle between the benzene rings is 5.11 (7). The crystal structure is determined mainly by intra-molecular C-H⋯O and inter-molecular π-π inter-actions. π-stacking between adjacent molecules forms columns with a parallel arrangement of the carbazole ring systems. The presence of the tert-but-oxy-carbonyl group on the carbazole N atom and the intra-molecular hydrogen bond induce a particular conformation of the exocyclic N-C bond within the mol-ecule.
