Abstract

In the title compound, C₂₁H₁₄BrN₃O₃, the indoline ring system is almost planar, while the pyran ring is in flattened-boat conformation. In the crystal, N-H⋯O and N-H⋯N hydrogen bonds link the mol-ecules, enclosing R ² ₂(8) and R ² ₂(12) ring motifs, into (001) sheets.

Keywords: crystal structure; hydrogen bond; indoline.
