The preparation of pyrimidine analogs of the 2,6-di-tert-butylphenol antiinflammatory agents Prifelone (R-830), Tebufelone (NE-11740) and Ym-13,162 is described. Grignard addition to the N-methoxy-N-methylamide derived from 4,6-bis(1,1-dimethylethyl)-5-hydroxy-2-pyrimidinecarboxylic acid yielded a series of 2-pyrimidinyl ketones. Further elaboration of an ethyl ketone and cyclization with sodium cyanate
描述了2,6-二叔丁基苯酚抗炎药Prifelone(R-830),Tebufelone(NE-11740)和Ym-13,162的嘧啶类似物的制备。从衍生自4,6-双(1,1-二甲基乙基)-5-羟基-2-嘧啶羧酸的N-甲氧基-N-甲基酰胺中加入格氏试剂,得到一系列2-嘧啶基酮。进一步精制乙基酮并用氰酸钠环化,得到嘧啶基咪唑。
