In the title compound, C14H15BrINO2, the conformation of the C—O—CH2—CH3 grouping is anti [torsion angle = 173.8 (6)°] and the bond-angle sum at the N atom bridging the two rings is 360°. An unusual intramolecular bifurcated N—H⋯(O,I) hydrogen bond helps to establish the molecular conformation, in which the I atom and the C=O grouping are syn. In the crystal, inversion dimers created by pairs of short intermolecular C—I⋯O interactions [C—I = 2.080 (7) Å; I⋯O = 3.211 (5) Å; C—I⋯O = 152.4 (2)°] occur.
