Procedure
[1-Oxo-2-(2-chloroallyl)-2-methyl-6,7-dichloro-5-indanyloxy]acetic acid is prepared following substantially the same procedure described in Example 4, Step D, using the following reagents: 2-(2-chloroallyl)-2-methyl-5-hydroxy-6,7-dichloro-1-indanone (4.8 g., 0.0157 mole), potassium carbonate (6.0 g.), ethyl bromoacetate (4.5 ml.) and DMF (55 ml.). The above procedure gives 2.7 g. (48%) of [1-oxo-2-(2-chloroallyl)-2-methyl-6,7-dichloro-5-indanyloxy]acetic acid which after recrystallization from butyl chloride melts at 160°-162° C.
