Procedure
Following the general procedure for Intermediate 2 using 4-fluoro-3-nitro-N,N-bis(2,2,2-trifluoroethyl)benzamide (100 mg, 0.287 mmol) and cyclohexylmethyl amine (0.041 mL, 0.315 mmol) in 3 mL of EtOH containing Et3N (0.080 mL, 0.574 mmol). The product was purified by flash chromatography on silica gel using 4:1/hexanes:EtOAc as eluent. Yield: 107 mg (85%); 1H NMR (CDCl3) 1.05 (m, 2H), 1.24 (m, 4H), 1.69 (m, 2H), 1.75 (m, 2H), 1.83 (m, 1H), 3.17 (t, J=6.64 Hz, 2H), 4.23 (q, J=8.53 Hz, 4H), 6.91 (d, J=8.98 Hz, 1H), 7.51 (d, J=8.89 Hz, 1H), 8.28 (s, 1H), 8.39 (s, 1H); MS (ESI) 442.29 (MH+).
