実験手順
To 3-ethyl-2,5-difluoro-4-(4-methyl-1-piperazinyl)nitrobenzene (1.12 g) are added potassium fluoride (0.24 g), N,N-dimethylsulfoxide (3.5 ml) and cyclopropylamine (0.4 ml), and the mixture is stirred at 80° to 85° C. for 1.5 hour. The reaction mixture is diluted with ethyl acetate, and the organic layer is washed with water and aqueous saturated sodium chloride and dried over magnesium sulfate and then concentrated under reduced pressure to give N-cyclopropyl-2-ethyl-3-(4-methyl-1-piperazinyl)-4-fluoro-6-nitroaniline (1.00 g), as viscous oil.
