Reaction Steps
In a 100 ml autoclave, 2 ml of ammonia are condensed and 2.0 g (6.4 mmol) of 4,5-difluoro-2-(bis-methanesulphonyl-amino)-benzonitrile and 40 ml of tetrahydrofuran are added. The reaction mixture is then heated in the closed autoclave at 150° C. for 15 hours. After cooling, the mixture is filtered and the filtrate is concentrated under water pump vacuum. Washing with 2N hydrochloric acid and with water gives 0.50 g (34% of theory) of N-(5-amino-2-cyano-4-fluoro-phenyl)-methanesulphonamide of melting point 235° C.
