Versuchsvorschrift

Into a round bottom flask was added 8-amino-1-(8-fluoro-2-phenyl-quinolin-7-yl)-2H-imidazo[1,5-a]pyrazine-3-thione (21 mg, 0.000053 mol), 4-bromobenzenediazonium tetrafluoroborate (0.018 g, 0.000064 mol) and dimethyl sulfoxide (0.1 mL, 0.002 mol) and the reaction mixture was stirred in ice for 30 min. The reaction mixture was cooled, dissolved in DCM and washed with water. Purification by Gilson HPLC eluting with 10→90% acetonitrile: H2O afforded the title compound as a yellow solid. 1H NMR (400 MHz, CDCl3): δ=7.13-7.17 (m, 2H), 7.23 (d, J=5.05 Hz, 1H), 7.42 (d, J=8.59 Hz, 2H), 7.49-7.59 (m, 3H), 7.61 (d, J=5.05 Hz, 1H), 7.75-7.78 (m, 2H), 8.05 (d, J=8.59 Hz, 1H), 8.22-8.27 (m, 2H), 8.32 (dd, J=8.72, 1.39 Hz, 1H). MS (ES+): m/z 544.15 (100)[MH+]. HPLC: tR=2.69 min (Open Lynx polar—5 min).
