Abstract (en)

[origin: WO9400433A1] This invention relates to a process of making a compound of formula (I) where R1 contains an (alpha),(beta)-unsaturated carbonyl group and Rn 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.
