실험 절차

4-Cyano-N-[2,6-dimethyl-4-(1,2,2,2-tetrafluoro-1-trifluoromethyl-ethyl)-phenyl]-3-nitro-benzamide (1.0 g, 2.16 mmol) (Example I1) was dissolved in diethylene glycol dimethyl ether (“diglyme”) (25 ml) and tin chloride (1.229 g, 6.48 mmol) was added. The mixture was cooled to 0° C. and aqueous hydrochloric acid (concentrated) (4 ml) was added slowly. The reaction mixture was stirred at 80° C. for 0.5 hours. Aqueous sodium hydroxide (30% w/v) (80 ml) was added to adjust the pH to 7-8. The aqueous phase was extracted three times with ethyl acetate (200 ml). The combined organic extracts were dried over sodium sulfate and concentrated. The residue was purified by column chromatography on silica gel (eluent: cyclohexane/ethyl acetate 1:1 to 0:1) to give 3-amino-4-cyano-N-[2,6-dimethyl-4-(1,2,2,2-tetrafluoro-1-trifluoromethyl-ethyl)-phenyl]-benzamide (0.48 g, 51% yield). 1H-NMR (400 MHz, CDCl3): 7.54 (s, 1H), 7.49 (d, 2H), 7.36 (m, 3H), 7.15 (q, 1H), 2.3 (s, 6H) ppm.
