Ethyl (Z)-3-(4-methylanilino)-2-[(4-methylphenyl)carbamoyl]prop-2-enoate
The title compound, C(20)H(22)N(2)O(3), is a secondary amine featuring an amide and an ester functionality in connection with a Michael system. The conformation about the C=C bond is E. Intra-molecular N-H⋯O hydrogen bonds occur. In the crystal, C-H⋯O contacts connect the mol-ecules into chains along the b-axis direction.

The asymmetric unit of the title compound, C(18)H(30)N(2)O(4), contains two independent mol-ecules. In each mol-ecule, the cyclo-hexane ring adopts a chair conformation with equatorial orientation of the substituents, and the conformation is stabilized by two intra-molecular N-H⋯O hydrogen bonds, forming rings of S(6) graph-set motif. One eth-oxy group and one ethyl group are disordered over tw...
