title: 3'-Hy-droxy-methyl-1'-methyl-3'-nitro-4'-(o-tol-yl)spiro-[indoline-3,2'-pyrrolidin]-2-one.
abstract: The title compound, C(20)H(21)N(3)O(4), crystallizes with two mol-ecules in the asymmetric unit. In both mol-ecules, the pyrrolidine ring adopts an envelope conformation. The crystal structure is stabilized by inter-molecular C-H⋯O, N-H⋯O and O-H⋯O hydrogen bonds.
