反応手順

Combine 4-fluoro-2-nitro-phenylamine (5.0 g, 32.03 mmol), 2-fluoro-5-trifluoromethyl-benzonitrile (6.07 g, 32.03 mmol) and lithium hydroxide monohydrate (4.03 g, 96.08 mmol) in methyl sulfoxide (DMSO, 60 ml). Heat the resulting mixture to 70° C. for 16 hours. Cool the reaction mixture to ambient temperature, then pour into approximately 400 ml of ice water and stir for one hour. Filter the resulting mixture and collect the precipitate to obtain 9.995 g of the title compound (30.73 mmol, 96% yield) as an orange amorphous solid. Product used as is with no further purification: Mass Spectrum (m/e): 326(M+1).
