Reaction Steps

5.2 g of 7-amino-2,3,5,6,7,8-hexahydronaphtho[2,3-b]furan dissolved in 27.6 ml of methylene chloride are stirred at room temperature in the presence of 8.3 ml of 40% strength sodium hydroxide, 3.3 g of allyl bromide and 1 ml of 40% strength Triton B in methanol. After 20 hours' stirring, 1 ml of Triton B is added again, followed by a further 2 ml after 24 hours' stirring. After 96 hours' stirring, the mixture is separated off after being left to settle and evaporated under vacuum. The residue, taken up in ethyl ether, is washed with water and then dried over anhydrous sodium sulfate. After evaporation, 4.6 g of base are obtained. The corresponding hydrochloride is obtained in acetonitrile by adding a stoichiometric quantity of ethereal hydrogen chloride, and then recrystallized in water.
