approach to 2‐amino‐5‐halogen‐pyrimidine‐4‐carboxylic acids from 5‐halogen‐2‐methylsulfonylpyrimidine‐4‐carboxylic acid by nucleophilic displacement of the methylsulfonyl group with primary and secondary aliphatic amines has been developed. The titled amino acids underwent decarboxylation, yielding 2‐amino‐5‐halogenpyrimidines. Starting from 2‐amino‐5‐chloropyrimidine‐4‐carboxylic acid chlorides, 2‐[5‐chl
摘要 已经开发了一种从 5-卤素-2-甲基磺酰基嘧啶-4-羧酸通过用脂肪伯胺和仲脂肪胺亲核取代甲基磺酰基来合成 2-氨基-5-卤素-嘧啶-4-羧酸的简便方法。标题氨基酸经过脱羧,产生 2-氨基-5-卤代嘧啶。以2-氨基-5-氯嘧啶-4-甲酰氯为原料,得到2-[5-氯-2-(氨基)-4-嘧啶基]-2-氧代-1-(2-吡啶基)-乙基氰化物以优异的产量。
