실험 절차

2,3-Difluoro-5-(trifluoromethyl)benzonitrile (60.03 g, 0.29 moles) is added to a solution of 17.5 g (0.43 moles) of sodium hydroxide in 158 ml of water. The mixture is heated to 97° C. during 1 hour and then heating is continued for an additional 2 hours. The mixture is acidified and the solid acid filtered off and air dried to yield 2,3-difluoro-5-(trifluoromethyl)benzoic acid, m.p. 94°-96° C.
