Three 2-methoxy-4-substituted pyrimidine compounds were chemoselectively synthesized by diazotization, using 2,4-dichloropyrimidine as the starting material. In nonaqueous diazotization reaction system, halo-substituted 6 and 7 were efficiently prepared, and in aqueous medium, hydrolysis product 8 was afforded.
三种2-甲氧基-4取代的嘧啶化合物通过重氮化反应选择性合成,采用2,4-二氯嘧啶作为起始材料。在无水重氮化反应体系中,氯取代的化合物6和7被高效制备,而在水相介质中,则获得了水解产物8。
