Reaction Steps
A stirred mixture of 2,2-diphenyl-5-hydroxy-6,7-dichloro-1-indanone (4.9 g., 0.0133 mole), potassium carbonate (3.68 g., 0.0266 mole) and ethyl bromoacetate (4.45 g., 0.0266 mole) in dimethylformamide (150 ml.) is warmed at 55°-60° C. for 3.5 hours, then treated with water (150 ml.)-10 N sodium hydroxide solution (7.5 ml., 0.075 mole) and heated at 90° C. for 1.5 hrs. The reaction mixture is added slowly to water (1 l.)-12 N hydrochloric acid (30 ml.) to precipitate 3.60 g. of (1-oxo-2,2-diphenyl-6,7-dichloro-5-indanyloxy)acetic acid which melts at 251°-252° C. after crystallization from first acetic acid, then nitromethane.
