Abstract
A modification of the method for the synthesis of N(1)-substituted derivatives of uracil is proposed using the Gilbert-Johnson reaction, which consists of the alkylation of 5-substituted 2,4-bis(trimethylsiloxy)pyrimidines with 1-bromo-2-(phenoxy)ethanes of low reactivity at 180-185° without solvent. The corresponding 1-[2-(phenoxy)ethyl]uracils, which were obtained in 55-74% yield, contained no impurities of the N(1), N(3)-disubstituted compounds.
