Reaction Steps

To 30 ml of ethanol, 1.2 g of 4-mercaptophenol, 2.1 g of 2-bromoethylamine hydrochloride and 1.4 g of potassium carbonate were added, followed by stirring for 3 hours at room temperature. Water was added, and the resulting mixture was extracted with ethyl ether. The extract was dried over MgSO4 and the ethyl ether was distilled off under reduced pressure, whereby 1.7 g of the compound (7) were obtained (yield: stoichiometric).
