Reaction Steps
The title compound was prepared according to the procedure of Example 7 using 5,6,7,8-tetrahydronaphthalene-1-ol (10 g, 0.067 mol) in methylene chloride (100 ml), sodium hydroxide (5.5 g, 0.134 mol) in water (100 ml), 1,3-dibromopropane (47 g, 0.23 mol) and tetra n-butylammonium bisulfate (23 g, 0.067 mol). Chromatography of the crude product on silica gel using 1% ethyl acetate/hexane as eluent gave 12 g (60%) of the title compound as an oil.
