Reaction Steps

A solution of 3-bromothiophenol (5.0 g) in 60 mL of DMF was treated with 3.75 g of ground potassium carbonate and 3.2 mL of 3,3-dimethylallyl bromide. The reaction mixture was stirred at room temperature for two hours, poured onto 75 mL of ice-water, acidified to pH 2.0 with 10% HCl and extracted with three 75 mL portions of ether. The organic phase was dried over MgSO4, filtered and concentrated in vacuo to give a yellow oil. The product was purified by short path distillation (T=170° C. at 950 mTorr) to give 5.651 g of 1-bromo-3-(3-methyl-but-2-enylsulfanyl)-benzene as a colorless liquid.
