4, 4''-Diamino-3, 3'', 5, 5''-tetraisopropyl-o-terphenyl is an important chemical intermediate, the target product is synthesized by four steps from 2, 6-diisopropyl aniline in this article. The optimal conditions of proparing target product are investigated in detail and the structures of the products produced in each step are characterized via 1HNMR. The results indicate that the yield of N-(4-bromo-2, 6-dissopropyl) benzophenone imine is up to 76% when 1-bromo-2, 6-diisopropyl aniline/benzophenone is 1/0.8 via removing the produced ethanol by nitrogen. 1 equiv of N-(4-bromo-2, 6-dissopropyl), 1.1 equiv of benzophenone imine and 1.1 equiv of triisopropyl borate are the optimal proportion to achieve 3, 3-dissopropyl-4-benzophenone amino phenybronic acid. The product results of 1HNMR analysis shows that 4, 4''-diamino-3, 3'', 5, 5''-tetraisopropyl-o-terphenyl is successfully synthesized.
