with methyl iodide. Formylation of 2 with formic acid afforded N-(1, 3- dimethyl-dioxo-tetrahydropyrimidin-4-yl)-formamide 3. The nitration of 3 gave N - (1,3-dimethyl-5- nitro-dioxo-tetrahydropyrimidin-4-yl) formamide 4. Reduction of 4 by zinc dust in glacial acetic acid yielded dimethyl-dihydro-purine-2, 6-dione 5. Addition of bromine to 2 leads to the formation of 6- amino-5-bromo-dimethyl-pyrimidine-2
