Ethyl 5,8-dibromo-2-dibromomethyl-6,7-dimethoxyquinoline-3-carboxylate

The title compound, C15H13Br4NO4, was obtained via radical bromination reaction of ethyl 6,7-dimethoxy-2-methylquinoline-3-carboxylate and N-bromosuccinimide (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 methoxy O atoms of the two neighboring methoxy 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.
