Hydrochloric Acid → 4-(2,2,2-Trifluoroethoxy)aniline

참여 물질

반응 단계

In a nitrogen atmosphere, 30.1 g (0.14 mol) of p-(2,2,2-trifluroethoxy) nitrobenzene, 82.1 g (1.47 mol) of reduced iron, 120 ml of ethanol and 40 ml of water were placed in a three-necked flask, to which 1.4 ml of concentrated hydrochloric acid was dropped under stirring and then refluxed for one hour. After cooling to a room temperature, it was separated by filtration, and the reaction solution was poured into iced water (about 2 liter), and precipitated solids were washed with water and then dried, to obtain 24.4 g (0.13 mol) of p-(2,2,2-trifluoroethoxy) aniline as pink solids. The yield was 94% and the melting point was 69.4° C.
