(2E)-2-(2,4-Dichloro-phenyl-sulfon-yl)-3-(4-methyl-anilino)-3-(methyl-sulfan-yl)acrylonitrile.

The title compound, C(17)H(14)Cl(2)N(2)O(2)S(2), and the 3-methoxy-anilino analogue reported in the preceding paper have been used as starting materials to develop benzothia-zine derivatives with anti-malarial activity. The mol-ecule displays an E (trans) configuration about the central double bond. Due to conjugation in the C=C-C N group, the putative single bond shows a significant shortening [1.
