Versuchsvorschrift
Acetylchloride (1.8 mL, 25.3 mmol) in 25 mL THF was added to a mixture of methyl 5-amino-2-difluoromethoxy-benzoate (5.40 g, 24.9 mmol) with TEA (4.5 mL, 32.4 mmol) in 50 mL THF and the resulting mixture stirred for 15 min at ambient temperature. The mixture was filtered and the filtrate concentrated i. vac. The residue was mixed with acetonitrile and water, concentrated i. vac. and the solid filtered off. It was washed with water and dried at 40° C.
