In a 1.3 l autoclave, 605 g (2 mol) of 2-chloro-3,3,4,4,5,5-hexafluorocyclopentenyl phenyl ether (from Step 1) are suspended in 500 ml of pH 9 buffer (bora/HCl), and the mixture is hydrogenated at 70°-80° C. with 80 bar hydrogen, using 50 g of palladium/charcoal. The catalyst is filtered off, and the filtrate is extracted with dichloromethane. Distillation gives 2,2,3,3,4,4-hexafluorocyclopentyl cyclohexyl ether.
