Reaction Steps

The title compound was prepared according to the procedure of Example 7 using 5,6,7,8 tetrahydro naphthalene-1-ol (8 g, 0.054 mol) in methylene chloride (100 ml), sodium hydroxide (4.32 g, 0.108 mol) in water (100 ml), 1,5-dibromopentane (37 g, 0.19 mol) and tetra n-butylammonium bisulfate (18.3 g, 0.054 mol). Chromatography of the crude product on silica gel using 20% ethyl acetate/hexane as eluent gave 12 g (69%) of the title compound as an oil.
