A mixture of 4-cyanothiophenol (20.8 g, 154 mmol), 1,3-dibromopropane is (155 g, 0.77 mol) and K2CO3 (21.3 g, 154 mmol) in MeCN (300 mL) was refluxed overnight. Filtration and evaporation of the solvent gave a brown oil that crystallised when treated with EtOH. The crystals were isolated by filtration to give the sub-title compound (24.5 g, 62%).
