Versuchsvorschrift
A solution of tert-butyl (1-oxo-2-methyl-2-phenyl-6,7-dichloro-5-indanyloxy)acetate (1.0 g., 0.00237 mole) in benzene (25 ml.) is treated with methanesulfonic acid (2 drops) and refluxed for 1/2 hour. The reaction mixture is treated with cyclohexane (20 ml.) and cooled affording (1-oxo-2-methyl-2-phenyl-6,7-dichloro-5-indanyloxy)acetic acid which is filtered and dried.
