本发明涉及一种新的氯甲基吡啶类化合物的制备方法以及所述制备过程中新的中间体化合物。
众所周知,氯甲基吡啶类化合物可以通过羟甲基吡啶类化合物与亚硫酰氯反应获得(参见J.Heterocycl.Chem.16(1979),333-337;也可参见EP-A 373 464)。
进一步公知的还有,氯甲基吡啶类化合物可在酸性中和剂或者可形成游离基的试剂存在下以及在惰性溶剂存在下,于0℃-100℃温度下,将甲基吡啶氯化获得(参见EP-A 260 485,也可参见EP-A 458 109)。
进一步公知的还有,通过与适宜的氯化剂反应,也可将烷氧基甲基吡啶类化合物转化为氯甲基吡啶类化合物(参见EP-A 393 453)。
众所周知的还有,氯甲基吡啶类化合物可以在例如氯化氢存在下将相应的氨甲基吡啶类化合物重氮化获得(参见JP 05 178 832)。
但是,对于这些公知的合成方法,它们所实现的产率以及产物的质量通常不能令人满意。
令人惊奇的是,尽管现有技术中,一方面,NH基团的甲酰化作用是可以预见的(参见,例如J.C.S.Perkin I,p1537-1543(1981)),而另一方面,该反应并没有用五氯化磷或亚硫酰氯作氯化剂进行“von Braun反应”(参见JACS84,769-774(1962)),因此,利用本发明的方法,可以以良好的产率以及较高的纯度获得式(I)的氯甲基吡啶类化合物。
