Procedure

(1-Hydroxy-2-isopropyl-2-methyl-6,7-dichloro-5-indanyloxy)acetic acid is prepared following substantially the same procedure described in Example 4, Step F, using the following substances: 2-methyl-2-isopropyl-6,7-dichloro-1,5-indandiol (8.3 g., .03 mole); potassium carbonate (7.2 g.); ethyl bromoacetate (6.2 ml.); and dimethylformamide (70 ml.); and hydrolyzing the resultant ester with aqueous sodium hydroxide in accordance with Example 4, Step F, gives (1-hydroxy-2-isopropyl-2-methyl-6,7-dichloro-5-indanyloxy)acetic acid.
