Reaction Steps

790 mg of N-(2-nitro-5-fluorophenyl)aminomethanephosphonic acid diethyl ester is mixed in 50 ml of ethanol with 2.5 g of Raney nickel and hydrogenated for 2 hours at room temperature under normal hydrogen pressure. After suctioning-off from the catalyst, it is concentrated by evaporation. 660 mg of N-(2-amino-5-fluorophenyl)aminomethanephosphonic acid diethyl ester is obtained.
