Procedure

A mixture of 165 mg of (2,2-dimethyl-1,3-dioxolan-4-yl)methyl [(5,6-dichloro-9a-ethyl-3-oxo-1,2,9,9a-tetrahydro-3H-fluoren-7-yl)oxy]acetate from Example 109, Step A is dissolved in 100 ml. of 0.075 N hydrochloric acid and 20 ml. of acetone and heated, with stirring at 50°-55° C. for 2 hours. The mixture is cooled and neutralized with a solution of sodium bicarbonate. The solution is saturated with sodium chloride and extracted two times with 100 ml. portions of 20% tetrahydrofuran in ether. The extract is dried over Na2SO4. After filtration, the filtrate was concentrated to a yellow oil that solidified on standing. After recrystallization from tetrahydrofuran-ether-petroleum ether, there is obtained 110 mg. of product, m.p. 135°-138° C.
