Reaction Steps

A solution of cis-1,9,10,10a-tetrahydro-4a(4H)-phenanthrenecarboxylic acid (25 g, 0.11 mole) and dimethylsulfate (11.4 ml, 0.12 mole) in 75 ml acetone was treated with potassium carbonate (20.7 g, 0.15 mole) and stirred overnight. An additional 5 ml dimethylsulfate was added and the reaction mixture was refluxed for 1 hour. After cooling the potassium carbonate was removed by filtration and the filtrate evaporated to give the title compound (27 g, quantitative). ##STR60##
