✦ Synopsis

In the title cocrystal, 0.972(C 18 H 19 NO 4 ).0.028(C 17 H 16 BrNO 3 ), which arose from an impure starting material, all the atoms are overlapped except for one OMe group and the Br atom. The dihedral angle between the benzene ring mean planes is 18.20 (13) . A weak N-HÁ Á ÁO hydrogen bond helps to establish the non-centrosymmetric crystal packing.
