According to the procedure of W. K. Anderson et al., J. Chem. Soc., Perkin 1, 1 (1976) a mixture of 4-bromothiophenol (40.0 g, 0.211 mol) and K2CO3 (35.3 g, 0.254 mol) was heated at reflux for 1 hour. 2,3-Dichloro-1-propene (23.5 g, 0.211 mol) was added. The resulting mixture was heated at reflux for 2 hours, cooled and concentrated. The mixture was diluted with H2O and extracted with ether (3×150 mL). The combined extracts were dried (MgSO4), and concentrated to give an oil. Distillation under high vacuum gave 37.2 g (67%) of product as a colorless liquid.
