In the title compound, C18H20BrNO3, the oxazolidine ring adopts an envelope conformation with the N atom at the flap position. The mean plane of oxazolidine ring makes dihedral angles of 82.96 (13) and 70.97 (12)°, respectively, with the phenyl and benzene rings. In the crystal, adjacent molecules are connected via O—H⋯O and C—H⋯O hydrogen bonds and C—H⋯π interactions into a zigzag chain along the b axis.
