Participants

Reaction Steps

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 added dropwise during a 10-minute period. The reaction mixture is refluxed for 5 hours, then evaporated to dryness at reduced pressure. The residue is dissolved in water, filtered and acidified with hydrochloric acid and affording α,α-dimethyl-(1-oxo-2-cyclopentyl-2-methyl-6,7-dichloro-5-indanyloxy)acetic acid.
