Reaction Steps
A suspension of 3-chloro-5-methoxyxanthone (5 g.) in dimethylformamide is added to a solution of excess sodium thiomethoxide in dimethylformamide (prepared from methyl mercaptan and sodium hydride). After 1 hour the reaction mixture is poured into water and extracted with ether, giving on evaporation 5-methoxy-3-(methylthio)xanthone, m.p. 201°-203° C. on recrystallisation from methanol.
