Reaction Conditions

Reaction Steps

A stirred solution of cupric chloride dihydrate (4.25 g. and lithium chloride (0.765 g.) in dimethylformamide (10 ml.) is heated to 90° C. and to the mixture is added a solution of methyl (1-oxo-2-ethyl-6,7-dichloro-5-indanyloxy)-acetate (4.7 g., 0.015 mole) in dimethylformamide. The reaction mixture is heated at 90° C. for two hours and poured onto ice. The product is extracted into ether (100 ml.), washed with water, dried over anhydrous sodium sulfate and the ether distilled at reduced pressure. There is thus obtained 2.5 g. of methyl (1-oxo-2-ethyl-2,6,7-trichloro-5-indanyloxy)acetate (53% yield) which melts at 111° C. after recrystallization from methanol.
