실험 절차

1 g. of 3-(2',4'-difluoro-4-biphenylyl)-3-hydroxybutyric acid ethyl ester, or the corresponding free hydroxy acid or 3-(2',4'-difluoro-4-biphenylyl)-2-butenoic acid, is heated with 2 ml. of 67% hydriodic acid and 4 ml. of acetic acid at 150° for 1 hour and the mixture is poured onto ice and decolorized with NaHSO3 solution. After the customary work up, 3-(2',4'-difluoro-4-biphenylyl)butyric acid, m.p. 109°-110°, is obtained.
