실험 절차

To a suspension of 9-benzenesulfonyl-3-bromo-5-(piperidin-4-yloxy)-9H-dipyrido[2,3-b;4′,3′-d]pyrrole-6-carbonitrile (450 mg, 0.88 mmol) in THF (8 mL) was added 2,2-difluoroethyl trifluoromethanesulfonate (282 mg, 1.32 mmol) in THF (1 mL), followed by DIPEA (250 μL). The resultant reaction mixture was heated at 65° C. for 7 hours, then concentrated in-vacuo. The residue was triturated with ethyl acetate to afford the title compound as a pale yellow solid (485 mg, 96%). 1H NMR (300 MHz, DMSO-d6): 9.46 (s, 1H), 8.90 (d, J=2.2 Hz, 1H), 8.70 (d, J=2.3 Hz, 1H), 8.24-8.23 (m, 2H), 7.78 (t, J=7.5 Hz, 1H), 7.64 (t, J=7.8 Hz, 2H), 6.13 (tt, J=55.8, 4.3 Hz, 1H), 4.85-4.85 (m, 1H), 3.17-3.12 (m, 2H), 2.75 (td, J=15.7, 4.3 Hz, 2H), 2.37 (t, J=10.9 Hz, 2H), 2.08-2.07 (m, 2H), 1.96-1.95 (m, 2H).
