Versuchsvorschrift
In 20 ml of a DMF solvent, 5.5 g (20 mmol) of 2-iodo-3,4-dimethyl-1-nitrobenzene and 10 g (155 mmol) of copper powder were heated at 150° C. for 48 hours. After the completion of the reaction, copper powder was removed by filtration and thereafter, the resultant was extracted using ethyl acetate, dried/concentrated, and then purified by column chromatography (ethyl acetate:hexane=1:10) to obtain 2.9 g (0.96 mmol) of 2,3,2′,3′-tetramethyl-6,6′-dinitrobiphenyl (34) (yield was 96%).
