Abstract

There are two independent mol-ecules in the asymmetric unit of the title compound, C(10)H(10)BrN(3)O(2), which are linked by N-H⋯O and C-H⋯O hydrogen bonds. The fused ring systems in both mol-ecules are nearly planar with maximum deviations of 0.001 (3) and 0.029 (3) Å. All non-H atoms of the first mol-ecule are approximately co-planar whereas in the second mol-ecule, the ethyl group is almost perpendicular to the imidazo[1,2-a]pyridine system, the C-O-C-C torsion angles in the carb-oxy-lic acid ethyl group being -179.8 (4) and 112.1 (5)°, respectively.
