実験手順

To a solution of N-[2,6-dimethyl-4-(1,2,2,2-tetrafluoro-1-trifluoromethyl-ethyl)-phenyl]-4-fluoro-3-nitro-benzamide (2.008 g, 4.4 mmol) (prepared according to WO 05/073165) in N,N-dimethylformamide (25 ml) was added sodium cyanide (0.237 g, 4.84 mmol). The reaction mixture was stirred at ambient temperature for 48 hours. Then water (20 ml) was added and the organic phase extracted three times with ethyl acetate (3×100 ml). The combined organic extracts were washed with water and brine, dried over sodium sulfate and concentrated. The residue was purified by column chromatography on silica gel (eluent: cyclohexane/ethyl acetate 1:4) to give 4-cyano-N-[2,6-dimethyl-4-(1,2,2,2-tetrafluoro-1-trifluoromethyl-ethyl)-phenyl]-3-nitro-benzamide (1.0 g, 49% yield). 1H-NMR (400 MHz, CDCl3): 8.85 (d, 1H), 8.38 (q, 1H), 8.11 (d, 1H), 7.55 (s, 1H), 7.40 (s, 2H), 2.33 (s, 6H) ppm.
