This invention relates to a process of making a compound of formula I ##STR1## where R.sub.1 contains an .alpha.,.beta.-unsaturated carbonyl group & R.sub.n is hydrogen or nonhydrogen radicals which do not have a functional group which interferes with the coupling reaction, which process comprises coupling a thiolphenol or phenylalkylmercaptan with a chloromethylpyridine in the presence of DBU under an inert atmosphere. These compounds are leukotriene antagonists and as such can be used in treating various diseases associated with leukotrienes.
本发明涉及一种制备I式化合物的方法,其中R.sub.1含有.alpha.,.beta.-不饱和羰基基团,R.sub.n为氢或非干扰偶联反应的官能团,所述方法包括在惰性气氛下,在DBU的存在下,将硫醇苯或苯基烷基硫醇与氯甲基吡啶偶联。这些化合物是白三烯拮抗剂,因此可用于治疗与白三烯有关的各种疾病。
