(E)-Methyl 2-(3-cinnamoyl-thio-ureido)acetate.

In the title compound, C(13)H(14)N(2)O(3)S, the methyl 2-(3-formyl-thio-ureido)acetate fragment and the phenyl ring adopt an E configuration. The mol-ecule exhibits an intra-molecular N-H⋯O hydrogen bond, which completes a six-membered ring. The crystal packing is stabilized by inter-molecular N-H⋯S contacts, generating a two-dimensional hydrogen-bonding network.
