Synthesis of 4-fluoro-1, 2-phenylenediamine CAS NO: 367-31-7 with 4-fluoroaniline as the starting material, the amino group was protected and nitrated in a one-pot method, and then deacetylated with 9 mol / L hydrochloric acid, and then Raney nickel was used to reduce 4-fluoro-1,2- Phenylenediamine. The total yield is 68.6%, and the product is characterized by 1H NMR and MS. This synthetic process improves the reaction yield, reduces the production cost, increases the stability of the reaction, and is conducive to industrial production.
