In the title compound, C(20)H(17)N(3), there are four mol-ecules in the asymmetric unit. The dihedral angles between the indolizine ring system and the pyridyl ring are 6.6 (2), 7.

Ethyl (E)-3-anilino-2-cyano-3-mercaptoacrylate.

In the title compound, C(12)H(12)N(2)O(2)S, there are S-H⋯N and N-H⋯O hydrogen-bond inter-actions. The N-H⋯O hydrogen bond is bifurcated, with the hydrogen being simultaneously donated to two equivalent O atoms, forming one intra- and one inter-molecular N-H⋯O bond with an R(1) (2)(4) motif. The motif of the S-H⋯N hydrogen bond is R(2) (2)(12).
