Reaction Steps

A stirred mixture of 2,3-diphenyl-2-methyl-5-hydroxy-6,7-dichloro-1-indanone (2.24 g., 0.00585 mole), potassium carbonate (1.62 g., 0.0117 mole) and ethyl bromoacetate (1.96 g., 0.0117 mole) in dimethylformamide (100 ml.) is warmed at 55°-60° C. for 3 hours, then treated with water (100 ml.)-10 N sodium hydroxide solution (5 ml., 0.05 mole) and heated at 90° C. for 1.5 hours. The reaction mixture is added slowly to water (1 l.) -12 N hydrochloric acid (10 ml.) to precipitate 1.14 g. of (1-oxo-2,3-diphenyl-2-methyl-6,7-dichloro-5-indanyloxy)acetic acid which melts at 203°-205° C. after crystallization from nitromethane.
