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.
