반응 단계
42.0 g (0.16 mol) of 2-methyl-1-nitroanthraquinone (0.16 mol) and 46.2 g (0.32 mol) of diethylaminodimethoxymethane (0.32 mol) in 150 g of diethylformamide are refluxed for 7 hours. After all the volatiles have been distilled off, the residue is slurried in water and filtered with suction, and the filter residue is dried under reduced pressure. This gives 49.6 g (90.0%) of 2-(2'-diethylaminoethenyl)-1-nitroanthraquinone; melting point: 235°-241° C. (with decomposition).
