Procedure
To a refluxing solution of 2-cyclopentyl-2-methyl-5-hydroxy-6,7-dichloro-1-indanone (15.5 g., 0.05 mole) in acetone (500 ml.) in an inert atmosphere is added solid sodium hydroxide (12.6 g., 0.25 mole). Chloroform (7.6 g., 0.69 mole) in acetone (50 ml.) is addded dropwise during a ten-minute period. The reaction mixture is refluxed for five hours, then evaporated to dryness at reduced pressure. The residue is dissolved in water, filtered and acidified with hydrochloric acid affording α,α-dimethyl-(1-oxo-2-cyclopentyl-2-methyl-6,7-dichloro-5-indanyloxy)acetic acid.
