In the title compound, C16H15BrN2O4, the six-membered carbocyclic ring of the chromene moiety adopts an envelope conformation with the disordered methylene C atom as the flap. The pyran ring is almost orthogonal to the chlorophenyl ring, making a dihedral angle of 87.11 (12)°. The amine-group N atom deviates significantly from the pyran ring [0.238 (3) Å]. The molecular structure is stabilized by an intramolecular N—HO hydrogen bond, which generates an S(6) ring motif. In the crystal, molecules are linked via C—HO hydrogen bonds, which generate C(8) chains running parallel to the b axis. The chains are linked by C—Hπ interactions. The methylene-group C atom of the chromene system that is disordered, along with its attached H atoms and the H atoms on the two adjacent C atoms, has an occupancy ratio of 0.791 (7):0.209 (7).
