The title compounds were readily synthesized in one pot by the reaction of methyltriethylammonium 2-(-methyl)--propenolate, formed directly by the reaction of methyl 2-(-methyl)-2-hydryl--propyl ether with two equivalents of triethylamine in DMF, and S-alkylisothiourea hydrogen halide, followed by the reaction with triethylamine again. Derivatizations via nucleophilic substitution of the fluorine atom
标题化合物很容易在一个锅中通过2-(-甲基)--丙烯酸甲基三乙基铵的反应合成,该反应是通过2-(-甲基)-2-羟丙基-丙基醚甲基与两当量的三乙胺的反应直接形成的在DMF中,与S-烷基异硫脲氢卤化物反应,然后再次与三乙胺反应。在标题化合物烷基化之后进行经由6-位氟原子的亲核取代的衍生化反应,从而制备出各种三氟甲基取代的嘧啶。
