    摘要: Thiolcarbonates represented by the formula, ##SPC1##Wherein R.sub.1 and R.sub.2 are individually a hydrogen atom or a methyl group, and R.sub.3 is a straight chain or branched chain saturated or unsaturated alkyl group having 1 to 5 carbon atoms or is a benzyl or benzhydryl group which may be nuclear substituted, are easily produced by reacting an alkali metal salt of 2-mercaptopyrimidine with phosgene, and reacting the resulting thiolchloroformate with an alcohol (R.sub.3 OH).

    摘要: Pyrimidine derivatives represented by the formula, ##SPC1##Wherein R.sub.1 and R.sub.2 are individually a hydrogen atom or a methyl group, and R.sub.3 is a group formed by removing the carboxyl group from a carboxylic acid, are quite useful in acylating compounds having amino and/or imino and/or hydroxyl groups. The pyrimidine derivatives can easily be prepared by reacting a 2-mercapto-4- and/or 6-methyl-substituted or unsubstituted pyrimidine with a carboxylic acid or a reactive derivative thereof in an inert solvent.
