The title compound, C(15)H(13)Br(4)NO(4), was obtained via radical bromination reaction of ethyl 6,7-dimeth-oxy-2-methyl-quinoline-3-carboxyl-ate and N-bromo-succinimide (NBS) in the presence of benzoyl peroxide (BPO) under photocatalytic conditions. The quinoline ring system is approximately planar with a maximum deviation from the mean plane of 0.035 (1) Å. The dihedral angle between the six-membered rings is 2.33 (2)°. The meth-oxy O atoms of the two neighboring meth-oxy groups are in-plane while their methyl C atoms are located on either side of the quinolyl ring plane at distances of -1.207 (1) and 1.223 (1) Å.
