Versuchsvorschrift

A solution of 5-chloro-2,4-difluorobenzoic acid (2.8 g, 15 mmol) in a solution of HCl in methanol (4 M, 10 mL) was stirred at 60° C. for 4 hours. The reaction was cooled down and the solvent was evaporated to afford the title compound, which was used for the next step without further purification.
