Reaction Steps
1-Chloro-2,5-difluoro-4-nitrobenzene (3.69 g, 19 mmol) is treated at 0° with diethylamine (2.3 g, 23 mmol) and cyclopropylamine (1.3 g, 23 mmol). After 1 hour at 0° the suspension obtained is stirred at 25° for 16 hours. The reaction mixture is taken up in water (150 ml) and extracted with ethyl acetate. The organic phase is washed with 10 percent sodium chloride solution and dried over magnesium sulfate. After distillation of the solvent the residue is recrystallized from ethanol (50 ml). There are obtained 3.5 g (79%) of 5-chloro-N-cyclopropyl-4-fluoro-2-nitroaniline with a m.p. of 73.5°-75.5°.
