실험 절차

A solution of 15.6 g (100 mmol) 2-amino-4-fluoronitrobenzene, 22.5 g (180 mmol) 4-fluorobenzylamine and 20.2 g (220 mmol) triethylamine in 150 ml dimethylsulfoxide is heated with stirring and under an inert gas atmosphere for 30 hours to 60°-70° C. When the reaction time is completed, the solvent is distilled off in a vacuum, the residue is taken up in 500 ml 0.5N hydrochloric acid and the mixture is stirred intensively at room temperature for 30 minutes. The precipitated solid is suction filtered and subjected to hot steam extraction with toluene. The product crystallizing out of the toluene after the mixture has been allowed to stand for twelve hours at 0°-4° C. is suction filtered and dried in a vacuum. 22.2 g (85 % of theory) are obtained. After being left to stand for 12 hours at 0°-4° C., 2-amino-4-(4-fluorobenzylamino)-nitrobenzene crystallizes out of the toluene phase as orange-yellow crystals.
