実験手順

5-Chloro-2-nitropyridine (8.0 grams) was added to a solution of 2.5 grams of sodium methanethiolate in 100 milliliters of ethanol at a temperature of 0° C. to which solution excess sodium methanethiolate was added portionwise. The resulting reaction mixture was then heated to reflux and refluxed for 15 hours with constant stirring. At the end of the 15 hours, the reaction mixture was filtered and allowed to concentrate to 75 milliliters. The reaction mixture was then permitted to cool and filtered again, yielding the desired 5-(methylthio)-2-nitropyridine; it was recrystallized from ethanol, m.p., 100.5°-02.5° C.
