title: 1-(2-Hy-droxy-eth-yl)-3-[(2-hy-droxy-eth-yl)amino]-4-(1H-indol-3-yl)-1H-pyrrole-2,5-dione.
abstract: There are four molecules in the asymmetric unit of the title compound, C(16)H(17)N(3)O(4), in which the dihedral angles between the indole ring system and maleimide ring are 4.5 (3), 8.3 (3), 8.4 (2) and 10.4 (2)°. In the crystal, mol-ecules are linked by numerous N-H⋯O and O-H⋯O hydrogen bonds, generating a three-dimensional network.
