Abstract
5-Cyanopyrimidine derivatives were synthesized starting from 5-aminopyrimidine derivatives through the extended Sandmeyer reaction, and then these compounds were hydrolyzed to obtain pyrimidine-5-carboxylic acids. According to this procedure, 5-cyanopyrimidine derivatives and pyrimidine-5-carboxylic acid derivatives have been prepared in 62% and 65% yields, respectively, without any difficulties in removing impurities.
5-Cyanopyrimidine 유도체를 5-Aminopyrimidine 유도체로부터 Sandmeyer반응에 의하여 합성하고 이 화합물들을 가수분해하여 Pyrimidine-5-carbolylic acid 을 합성하였다. 이 방법에 의하면 불순물 제거의 어려움 없이 5-Cyanopyrimidine유도체와 Pyrimidine-5-carboxylic acid유도체를 62%와 65%의 수율로 합성할 수 있었다.
