반응 단계
Heat a solution of 2-amino-5-isopropyl-benzonitrile (1.482 g, 9.25 mmol) with 1,4-difluoro-2-nitro-benzene (1.47 g, 9.25 mmol) and lithium hydroxide monohydrate (0.78 g, 18.50 mmol) in DMSO (20 ml) to 70° C. for 38 hours. Cool the reaction to ambient temperature and pour into approximately 200 ml of ice water and stir for one hour. Collect by filtration the title compound which precipitates. No further purification is necessary to obtain 2.236 g (7.47 mmol, 81% yield) of the title compound as an orange amorphous solid: Mass Spectrum (m/e): 300(M+1).
