According to the procedure of W. K. Anderson, J. Chem. Soc., Perkin, 1, 1 (1976), a mixture of 3-(4-bromothiophenoxy)-2-chloro-1-propene (37.4 g, 0.142 mol) and N,N-diethylaniline (180 mL) was heated to 210°-215° C. for 2 days, cooled, and diluted with ether. The ethereal layer was washed with 10% HCl (3×200 mL), dried (MgSO4), and concentrated. Purification by column chromatography (eluant: hexane) gave 15.0 g (46%) of product as a white solid.
