反応手順
To a mixture of N-(β-hydroxyethyl)diethylamine (5.86 g) and 2,4-diaminobenzene sulphonic acid (7.52 g) in dimethylsulphoxide (45 cm3) was added 1,2,4,5-tetrafluoro-3,6-dicyanobenzene (8.25 g) portionwise with stirring. The mixture was heated at 75° C. for 4 hours then poured into ice/water (140 cm3) to give a solution of 2-amino-4-(2,4,5-trifluoro-3,6-dicyanophenylamino)benzene sulphonic acid.
