A novel 2-lower alkyl-4-amino-5-substituted iminopyrimidine compound represented by the formula: ##STR1## wherein R is a lower alkyl, and Y is hydroxyl or amino which may be protected or a salt thereof is obtainable by allowing a formylpyrimidine compound represented by the formula: ##STR2## wherein R is a lower alkyl to react with a compound represented by the formula H.sub.2 N--Y, wherein Y is hydroxyl or amino which may be protected, or a salts thereof. The iminopyrimidine compound gives the known pyrimidine compound represented by the formula: ##STR3## wherein R is as defined above in high yield. Therefor, the process is very useful as an industrial production method.
一种由以下公式表示的新型2-较低烷基-4-氨基-5-取代亚氨基嘧啶化合物:其中R为较低烷基,Y为羟基或氨基,可能被保护或其盐,可通过允许由以下公式表示的甲酰基嘧啶化合物与由以下公式表示的化合物H.sub.2 N-Y发生反应而获得:其中R为较低烷基,Y为羟基或氨基,可能被保护,或其盐。该亚氨基嘧啶化合物以高产率提供了所知的由以下公式表示的嘧啶化合物:其中R如上所定义。因此,该过程作为工业生产方法非常有用。
