5-Hydroxy-3,6-dimethyluracil, 5-methoxy-1,3,6-trimethyluracil, earlier unknown 5-methoxy-6- methyluracil, 5-methoxy-1,6-dimethyluracil, and 5-methoxy-3,6-dimethyluracil have been synthesized via alkylation of 5-hydroxy-6-methyluracil with dimethylsulfate in aqueous-alkaline media. The obtained compounds have been identified using 1Н, 13С, and 15N NMR spectroscopy.
