Abstract:
The title compound, C(28)H(27)N(3)O(4)S, crystallizes in the centrosymmetric space group P2(1)/n, with one molecule in the asymmetric unit. In the indole ring, the dihedral angle between the fused rings is 3.6 (1) degrees. The phenyl ring of the sulfonyl substituent makes a dihedral angle of 79.2 (1) degrees with the best plane of the indole moiety. The phenyl ring of the dimethylaminophenyl group is orthogonal to the phenyl ring of the phenylsulfonyl group. The dihedral angle formed by the weighted least-squares planes through the pyrrole ring and the phenyl ring of the dimethylaminophenyl group is 7.8 (1) degrees. The molecular structure is stabilized by C-H.O and C-H.N interactions.
