The nitration of 4-phenylpyrimidine using nitric acid/sulphuric acid at 0 deg C has been shown to give 4-o-nitrophenylpyrimidine and 4-m-nitro-phenylpyrimidine in the ratio of 4:6.Under similar conditions 5-bromo-2-phenylpyrimidine has given 5-bromo-2o-nitrophenyl and 5-bromo-2-m-nitrophenylpyrimidine in the ratio of 3:7 and 5-chloro-2-phenylpyrimidine has given the 2-o-nitrophenyl and the 2-m-nitrophenyl isomers in the ratio of 3.5:6.5.
