in a four-neck bottle, under stirring, 0.02mol p-toluenesulfonic acid is added to 0.1mol aniline, N2 gas is replaced, 0.3mol HFA 3H2O is slowly added dropwise in a heated state (about 30min dropwise), the reaction is stopped after the dropwise addition is completed, the reflux is continued at 110 ℃ for 8h, and the reaction is stopped, and the reaction is cooled to room temperature to become a white solid. Add ether to dissolve, filter and wash. The filtrate is evaporated by rotation to remove ether and other low boiling point substances, and after drying, 2-(4-aminobenzene)-1,1,1,3,3, 3-hexafluoro-2-propanol crude product, yield The rate is 90.2%(GC-MS), and the purity is 97.9%.
