chemoselective alkylation, benzylation, and arylation of C-5 and C-6 substituted pyrimidine nucleobases selectively at the N-3 position. The reactions were found to proceed, with high efficiency, without the requirement of solvent and were complete within 10–15 min of irradiation. The efficiency of the method was further improved by addition of a Lewis acid, which not only increases the yield significantly but
