The title compound, C19H18BTNO3, has potential calcium modulatory properties. The 1,4-dihydropyridine ring has a very shallow boat conformation and is one of the most planar examples of this moiety. The 2-bromophenyl substituent is in the axial synperiplanar orientation. The quinoline ring has a half-chair conformation, with the unusual arrangement of the out-of-plane atom being on the opposite side of the ring plane to the bromophenyl substituent. The molecules are linked into chains by intermolecular hydrogen bonds.
