Methyl 4-(4-bromo-anilino)-2',5-dioxo-5H-spiro-[furan-2,3'-indoline]-3-carboxyl-ate.

ABSTRACT: In the title compound, C19H13BrN2O5, the spiro furan ring is almost planar with a maximum deviation of 0.034 (2) Å. The indole unit and the furan ring are normal to each other, making a dihedral angle of 87.82 (8) °. The mol-ecular structure is stabilized by an intra-molecular N-H⋯O hydrogen bond, which generates an S(6) ring motif. In the crystal, mol-ecules are linked via pairs of N-H⋯O hydrogen bonds, forming inversion dimers enclosing R (2) 2(8) ring motifs.
