Versuchsvorschrift

To a suspension of 9-benzenesulfonyl-3-bromo-5-(piperidin-4-yloxy)-9H-dipyrido[2,3-b;4′,3′-d]pyrrole-6-carbonitrile (400 mg, 0.78 mmol) in methanol (10 mL) was added methyl vinyl sulfone (207 mg, 1.95 mmol). The resultant reaction stirred at ambient temperature for 24 hours, then concentrated in-vacuo. The residue was triturated with ethyl acetate to afford the title compound as a pale yellow solid (446 mg, 92%). 1H NMR (300 MHz, DMSO-d6): 9.46 (d, J=0.4 Hz, 1H), 8.90 (d, J=2.2 Hz, 1H), 8.67 (d, J=2.3 Hz, 1H), 8.24-8.24 (m, 2H), 7.78 (t, J=7.4 Hz, 1H), 7.64 (t, J=7.8 Hz, 2H), 4.86-4.86 (m, 1H), 3.27 (t, J=7.1 Hz, 2H obscured solvent peak), 3.03 (s, 3H), 2.92-2.80 (m, 2H), 2.73 (t, J=6.8 Hz, 2H), 2.21 (t, J=10.9 Hz, 2H), 2.22-1.98 (m, 2H), 1.92-1.92 (m, 2H).
