title: 1'-Methyl-4'-(4-methyl-phen-yl)dispiro-[1-benzopyran-3(4H),3'-pyrrolidine-2',3''-indoline]-2,2''-dione.
abstract: In the title compound, C(27)H(24)N(2)O(3), the pyrroldine ring adopts a twist conformation, while the six-membered pyran-one ring of the coumarin ring system is in a sofa conformation. In the crystal, pairs of N-H⋯O hydrogen bonds link the mol-ecules into inversion R(2) (2)(8) dimers. These dimers are further connected via C-H⋯O hydrogen bonds.
