4-Chlorodifluoromethoxyaniline has been used as a reactant for the preparation of arylphthalazines as a potent and orally bioavailable inhibitor of VEGFR-2. | [Synthesis]
General procedure for the synthesis of 4-(chlorodifluoromethoxy)aniline from 1-(chlorodifluoromethoxy)-4-nitrobenzene: 167 g of 1-(chlorodifluoromethoxy)-4-nitrobenzene was added to an autoclave, followed by the addition of 200 g of ethyl acetate and 15 g of nickel Nguyenne. After changing to a nitrogen atmosphere, hydrogen was introduced and the pressure in the autoclave was maintained at 2~3 MPa, and the reaction temperature was controlled at 30-40 °C. After the system pressure was stabilized and no longer decreased, the reaction was continued for 1 hour. Upon completion of the reaction, samples were taken and analyzed to ensure that the residual nitro compounds in the hydrogenation reaction solution were less than 0.5%. Subsequently, the catalyst was removed by filtration, and most of the solvent was firstly recovered by distillation at atmospheric pressure, and then purified by decompression distillation, finally 92.6 g of 4-(chlorodifluoromethoxy)aniline was obtained with a yield of 64.2%. | [References]
