In the title compound, C(16)H(15)N(3)O(4), the dihedral angle between the chromane and isoxazole rings [r.m.s. deviations = 0.042 and 0.007 Å, respectively] is 20.33 (12)°. The mol-ecular geometry is stabilized by an intra-molecular N-H⋯O hydrogen bond. In the crystal, N-H⋯O hydrogen bonds generate...

Zusammenfassung:In the title compound, C(16)H(15)N(3)O(4), the dihedral angle between the chromane and isoxazole rings [r.m.s. deviations = 0.042 and 0.007 Å, respectively] is 20.33 (12)°. The mol-ecular geometry is stabilized by an intra-molecular N-H⋯O hydrogen bond. In the crystal, N-H⋯O hydrogen bonds generate chains along the c-axis direction. The crystal studied was a non-morohedral twin.
