In the title compound, C(17)H(15)N(3)O(4), the atoms of the spiro pyran ring are nearly planar with a maximum deviation of 0.0188 (14) Å. The benzene and pyrrole rings make a dihedral angle of 5.71 (6)°. The indole system and the pyran ring are oriented at a dihedral angle of 82.94 (3)°. The crystal structure is stabilized by inter-molecular classical and non-classical N-H⋯O, N-H⋯N and C-H⋯O hydrogen bonds. ...[more]
