How is 3-(1,1,2,2-Tetrafluoroethoxy)aniline (CAS: 831-75-4) typically synthesized?

3-(1,1,2,2-Tetrafluoroethoxy)aniline (CAS: 831-75-4) is commonly synthesized through the reaction of aniline with 1,1,2,2-tetrafluoroethanol in the presence of a suitable catalyst, such as a strong base like sodium hydride. The process involves dehydrating the alcohol to form the corresponding anilide, followed by hydrolysis to introduce the tetrafluoroethoxy group. The overall yield of the reaction is typically around 70-80%.
