実験手順
When the formation of hydrogen had ceased (in about 30 min) 456 g (2 mole) of 1,2-dimethoxy-4,5-dinitrobenzene were added and the reaction mixture was refluxed for 2 h. To the solution, 4 l of methanol and 300 ml of water were added. Upon cooling in ice a precipitate was formed which was filtered off and dried. Yield: 369 g (64%); melting point: 141° C.
