摘要
Abstract
Sodium 2-thiobarbiturate was synthesized from the reaction of thiourea and diethyl malonate, with 96.7% yield.4, 6-Dihydroxy-2-methylthiopyrimidine was prepared by methylation of sodium 2 - thiobarbiturate, with 86.9% yield.4, 6- Dichloro- 2- methylthiopyrimidine was achieved by chloration, with 91.5% yield.The total yield was 76.9%.The content of the product was more than 99.0%.The structures of the intermediates and target product were identified by IR and 1H NMR.关键词
