Cyclohexylamine (0.67 mL, 5.85 mmol) was added to a solution of Compound 6 (1.0 g, 2.92 mmol) in toluene (20 mL) and refluxed for 4 h. The solution was cooled and the solvent was evaporated under vacuum. The residue obtained was suspended in water, briefly sonicated, and filtered. The crude product was recrystalized by ether to yield 1.0 g (87%) of white solids. M.P. 168° C. 1H NMR (DMSO-d6): δ 1.26 (m, 1H), 1.36 (m, 4H), 1.55 (m, 1H), 1.68 (m, 2H), 1.89 (m, 2H), 3.88 (m, 1H), 5.51 (s, 2H), 7.13 (m, 2H), 7.25 (m, 2H), 7.33 (t, J=7.5 Hz, 1H), 7.45 (d, J=8.5 Hz, 1H), 7.70 (t, J=8.4 Hz, 1H), 8.12 (d, J=7.9 Hz, 1H), 10.35 (s, 1H), 17.66 (s, 1H). EIMS m/z 395 (M+1), 417 (M+23). Anal. (C23H23FN2O3) C, H, N.
