Reaction Steps

A mixture of 5,6-dichloro-9a-ethyl-7-hydroxy-1,2,9,9a-tetrahydro-3H-fluoren-3-one (6.0 gm., 0.02 mole), ethyl bromoacetate (4.0 gm., 0.025 mole) and potassium carbonate (8.3 gm., 0.06 mole) in dimethyl-formamide (35 ml.) is heated at 50° C. and stirred for one hour. The mixture is cooled and poured into water (300 ml.). The solid product that separates is removed by filtration, then washed with water followed by benzene (10 ml.).
