A reaction of 2-(bromomethyl)thioxanthone with sodium methanethiolate with sodium methanethiolate gave 2-(methylthiomethyl)thioxanthone (II) which was transformed by treatment with 3-dimethylaminopropylmagnesium chloride to the tertiary alcohol IV. Its dehydration by heating with dilute sulfuric acid afforded the title compound I. An attempt at preparing the analogous 2-(methoxymethyl) derivative proceeded similarly but failed in the stage of the acid-catalyzed dehydration of the tertiary alcohol V. Acids VIII-XII and the nitrile XIII were prepared as potential intermediates. Compound I has properties of a tranquilizer with a weak cataleptic activity.
2-(溴甲基)噻吩酮与甲硫醇钠反应生成2-(甲硫甲基)噻吩酮(II),经3-二甲氨基丙基镁氯化物处理转化为三级醇(IV)。通过加热稀硫酸脱水得到目标化合物(I)。尝试制备类似的2-(甲氧基甲基)衍生物时,酸催化的三级醇(V)脱水阶段失败。酸(VIII-XII)和腈(XIII)作为潜在中间体进行了制备。化合物(I)具有镇静剂性质和微弱的猫病活性。
