Abstract N‐Arylation of somepyrimidine and purine nucleobases in the presence of SiO2 and Cs2CO3 under solvent‐free as well as in solution conditions is described. In these conditions, N1‐aryl pyrimidines and N9‐aryl purines have been obtained regioselectively in moderate to high yields with relatively short reaction times.

A highly efficient and simple method for the synthesis of N-aryl derivatives of pyrimidine and purine nucleobases via N-arylation of nucleobases using zinc oxide in 1-butyl-3-methylimidazolium bromide ([bmim]Br) under microwave as well as thermal conditions is described. In both conditions, the title compounds were produced in high to excellent yields and in short reaction times.
