Abstract:
We have studied the catalytic hydrogenation of 2,5-bis(p-nitrophenyl)pyrimidine over palladium on carbon under different conditions. We have established that hydrogenation in acetic acid at atmospheric hydrogen pressure leads to formation of 2,5-bis(p-aminophenyl)-1,4,5,6-tetrahydropyrimidine. Upon hydrogenation under pressure in DMF, along with 2,5-bis(p-aminophenyl)pyrimidiine, three isomeric (aminophenyl)pyrimidyl-substituted benzenes are formed as by-products. The mixture of these arylazo derivatives can be smoothly reduced by hydrogen under pressure in the presence of Raney nickel to bis(aminophenyl)pyrimidine. © 1994 Plenum Publishing Corporation.
