実験手順

A solution of 23.5 g of chloroethyldimethylamine.HCl in 75 ml of ethanol was added to 160 ml of sodium hydroxide solution formed by dissolving 20 g of sodium hydroxide pastilles in 500 ml of ethanol. A solution of 30 g of 4-bromothiophenol in 100 ml of ethanol was added to 160 ml of the said sodium hydroxide solution and the first solution was added thereto over 2 minutes at 20° C. The mixture was refluxed for 3 hours and was evaporated to dryness. Water was added to the residue and the mixture was extracted with methylene chloride. The organic phase was washed with aqueous 0.1N sodium hydroxide solution, then with water, dried and evaporated to dryness. The residue was distilled to obtain 35.5 g of 4-(N,N-dimethylaminoethylthio)-bromobenzene boiling at 110° C. at 0.1 mm Hg.
