Reaction Steps

4.0 g (23.8 mmol) of 2-methoxy-5-nitroaniline were dissolved in 10 ml of N-methyl-2-pyrrolidinone, and 5.2 g (23.8 mmol) of 2-chloro-4,5-difluorobenzoyl isocyanate were added. Slight warming occurred. After 15 minutes at room temperature, diethyl ether was added, and the resulting precipitate was filtered off with suction. 6.6 g (79%) of the desired product were obtained.
