Versuchsvorschrift
A mixture of ethyl 2,4-difluoro-5-nitrobenzoate (5.00 g; 21.6 mmol) (see Example 59 (d)) in THF (100 mL) was treated with NH3 in THF (2.7 mL; 8 M; 21.6 mmol) at 0° C. and the mixture was stirred over night. Another portion of NH3 in THF (1.0 mL; 8M; 8 mmol) was added and the mixture stirred over night. Water (100 mL) was added and the mixture was concentrated. The precipitate was filtered off and dried to give the sub-title compound.
