실험 절차
36 g of 3-bromothiophenol were dissolved in 400 ml of dimethylformamide. After the addition of 27 g of finely powdered potassium carbonate and 29 g of 3,3-dimethylallyl bromide, the mixture was stirred at room temperature for 1 hour, diluted with 500 ml of water, acidified with 3N hydrochloric acid while cooling and extracted with ether. The yellow-brown oil obtained after evaporation was distilled in a high vacuum. There were obtained 48 g of m-bromophenyl 3-methyl-2-butenyl sulfide as a colorless liquid, boiling point 85° C./13.3 Pa.
