title: N-[(3RS,4SR)-1-Benzyl-4-methyl-piperi-din-3-yl]-1-(4-methylphenyl-sulfonyl)-5-nitro-1H-pyrrolo-[2,3-b]pyridin-4-amine.
abstract: The structure of the title compound, C(27)H(29)N(5)O(4)S, displays an intra-molecular N-H⋯O hydrogen bond. The pyrrolo-[2,3-b]pyridine core makes a dihedral angle of 85.5 (4)° with the benzyl residue and a dihedral angle of 89.4 (9)° with the tosyl ring. The nitro group is slightly twisted out of the plane of the planar pyrrolo-pyridine system [(-N-)C-C-N-O torsion angle = -4.61 (18)° and (-NH-)C-C-N-O = -6.46 (18)°].
