실험 절차

To 1-[3-(methyloxy)-4-nitrophenyl]-4-(4-piperidinyl)piperazine (Example 89, step D) (0.958 g, 2.99 mmol) and Na2CO3 (0.470 g, 4.43 mmol) in acetonitrile (20 mL) was added iodofluoroethane (0.500 mL, 6.15 mmol) in one portion. The resultant mixture was heated at 70° C. for 48 h. When complete by TLC, the reaction was poured into H2O (150 mL), extracted with DCM and EtOAc, dried (MgSO4) and concentrated. Purification by flash chromatography provided the title compound of step A (0.972 g, 2.63 mmol, 88%). 1H NMR (400 MHz, DMSO-d6) δ ppm 1.32-1.43 (m, 2H), 1.70 (d, J=15.0 Hz, 2H), 1.94 (t, J=12.5 Hz, 2H), 2.12-2.21 (m, 1H), 2.50 (t, J=5.0 Hz, 1H), 2.52-2.58 (m, 5H), 2.88 (d, J=10.4 Hz, 2H), 3.35-3.40 (m, 4H), 3.86 (s, 3H), 4.46 (dt, JHF=47.8 Hz, J=4.9 Hz, 2H), 6.47 (d, J=2.4 Hz, 1H), 6.54 (dd, J=9.3, 2.1 Hz, 1H), 7.83 (d, J=9.3 Hz, 1H).
