Ethyl 5-bromo-3-ethoxycarbonylamino1-benzofuran-2-carboxylate

In the title compound, CAH(14)BrNO(5), the ester group is disordered [occupancy ratio 0.52 (2):0.48 (2)]. The major component is nearly coplanar with the benzofuran plane, subtending a dihedral angle of 7.84 (2)degrees, while the amide group is twisted out of the benzofuran plane making a dihedral angle of 39.69 (2)degrees. An intramolecular N-H center dot center dot center dot O hydrogen bond occurs. In the crystal, pairs of weak C-H-center dot center dot center dot H hydrogen bonds link the molecules into inversion dimers, which are further linked via strong N-H-center dot center dot center dot O hydrogen bonds, generating a zigzag chain extending along [100].
