Reaction Steps

A mixture containing [(5,6-dichloro-9a-ethyl-3-oxo-1,2,9,9a-tetrahydro-3H-fluoren-7-yl)oxy]acetic acid (Example 20, Step D) (1.07 g, 0.003 mole), potassium carbonate (0.41 g, 0.003 mole) and benzyl bromoacetate (0.69 g, 0.003 mole) in dimethylformamide (35 ml) is heated at 80° C. for two hours. Then this mixture is filtered and the filtrate is concentrated in vacuo. The residue is dissolved in methylene chloride, washed with aqueous sodium bicarbonate and than water, dried over anhydrous magnesium sulfate and concentrated in vacuo to give a viscous oil which is triturated with ether to give 1.06 g. of product.
