Abstract: In the title compound, C21H21BrClNO4, the dihydropyridine ring adopts a flattened boat conformation. The 3-bromo-5-chloro-2-hydroxyphenyl ring forms a dihedral angles of 84.44 (7)° with the dihydropyridine mean plane. The molecular conformation is stabilized by an intramolecular O-HO hydrogen bond, with an S(8) ring motif. In the crystal, O-HO and C-HO hydrogen bonds link the molecules, forming a three-dimensional network.
