Versuchsvorschrift
2-Carboxy 2-difluoromethyl 5-hexenoic acid, prepared as in Step C (1.040 g, 5 mM) is dissolved in glacial acetic acid (5 ml) and the mixture is heated at 110° C. for 16 hours. The solvent is evaporated in vacuo yielding a colorless oil. The acid is isolated by distillation under reduced pressure. 0.585 g (yield 71%). Bp: 67° C./0.01 mm Hg.
