실험 절차

To a solution of 1.14 g (0.0055 mole) of 3-methoxy-2,4,5-trifluorobenzoic acid (XXVI) (prepared as described in Preparation 1 or 2) in 10 ml of dry benzene was added 5 ml of thionyl chloride and the mixture was heated under reflux for 1 hour. At the end of this time, benzene and the excess of thionyl chloride were removed completely to give 3-methoxy-2,4,5-trifluorobenzoyl chloride (XXVII) [Step (E7)].
