Ethyl (2E,4Z)-5-diethyl-amino-2-(phenyl-sulfon-yl)penta-2,4-dienoate.
In the title compound, C(17)H(23)NO(4)S, the penta-diene group adopts a planar conformation, with an r.m.s. deviation of 0.0410 (14) Å. The phenyl ring makes a dihedral angle of 85.73 (11)° with the penta-diene group, while the penta-diene group makes dihedral angles of 11.38 (11) and 14.08 (10)°, respectively, with the amino and ester groups. In the crystal, molecules are linked via pairs of C-H⋯O inter-actions, forming inversion dimers.
