Versuchsvorschrift

In a 5-liter three-necked round-bottomed flask was placed 180 g of the previously prepared 4-amino-3-chloro-5-methoxyiminomethylbenzoic acid, 2 l of toluene, 3 mL of dimethylformamide and 104 g (64 mL) of thionyl chloride. The resulting mixture was heated at 70° C. for 2 hours, filtered while hot and the solvent removed using a rotary evaporator yielding 178.1 g of the expected 4-amino-3-chloro-5-methoxyiminomethylbenzoyl chloride.
