The sulfone was prepared by using similar chemistry to that described earlier in reference [6]. For the use of benzothiazolyl sulfones in olefination reactions, see: a) J. B. Baudin, G. Hareau, S. A. Julia, O. Ruel, Bull. Soc. Chim. Fr. 1993, 130, 336-357; b) J. B. Baudin, G. Hareau, S. A. Julia, R. Lorne, O. Ruel, Bull. Soc. Chim. Fr. 1993, 130, 856-878.
