Abstract
In this work the alkylation of 2-ethylsulfanyl-5-methoxy-4(3)-pyrimidinone with 4-substituted w-bromoacetophenones was investigated. It was found that reaction of title compounds in the presence of potassium carbonate in boiling acetonitrile yielded O-alkylated derivatives with small amount of N3-alkylation products. N1-Alkylated izomers were not isolated or detected. The proportion of O- and N3-alkylated products varied depending on the nature of substituent in the 4th position of benzene ring. Distribution of O- and N-substituted isomers was estimated by means of H NMR spectra of crude product. The IR, UV and NMR spectral characteristics of alkylation products are in agreement with the proposed structures.
