(Z)-Ethyl 3-(2,6-diisopropylanilino)but-2-enoate

Abstract

The title compound, C18H27NO2, crystallizes as the enamine form with Z geometry. The β-enaminoester fragment forms a dihedral angle of 87.5 (1)° with the isopropylphenyl frame. The structure exhibits an intramolecular N—H...O hydrogen bond. In addition, in the crystal, molecules are linked by a centrosymmetric intermolecular N—H...O hydrogen bond.
