Abstract4,6-Dimethyl-2-methanesulfonylpyrimidine is an important intermediate for the synthesis of many biologically active compounds. The target compound was prepared in overall yield of 71.0% starting from thiourea via methylation with dimethyl carbonate, condensation with acetylacetone, and oxidation by hydrogen peroxide. The structure of target compound was characterized by 1H NMR and GC-MS spectra. |
Key words4,6-dimethyl-2-methanesulfonyl pyrimidine; thiourea; acetylacetone |
