Procedure

A stirred mixture of 48.0 g (24.0 g real, 0.60 mol) of 50% sodium hydroxide, 21.78 g (0.0791 mol) of α-isopropyl-p-(1,1,2,2-tetrafluoroethoxy)phenylacetonitrile, and 240 ml of ethylene glycol is heated at 135° C. for 12 hours. After dilution with 600 ml of water the reaction mixture is washed twice with 100 ml of ether. The water layer is acidified with concentrated hydrochloric acid and then extracted twice with 300 ml of ether. The ether solution is washed twice with 500 ml of water, dried with sodium sulfate, filtered, and then evaporated to give 20.74 g (89%) of a brown solid, melting point 92° C. to 97° C. (hexane).
