실험 절차

1 g. of 3-(2',4'-difluoro-4-biphenylyl)butyronitrile and 6 ml. of acetic acid and 6 ml. of concentrated hydrochloric acid are heated under reflux for 2 hours under nitrogen. The mixture is evaporated. The residue is dissolved in dilute NaOH and the solution is washed with ether and worked up in the customary manner to give 3-(2',4'-difluoro-4-biphenylyl)butyric acid, m.p. 109°-110°.
