Versuchsvorschrift

A 10 mL microwave vessel was charged with a solution of 8-amino-1-(8-fluoro-2-phenyl-quinolin-7-yl)-2H-imidazo[1,5-a]pyrazine-3-thione (10 mg, 0.00002 mol), 2-chloropyrimidine (0.0059 g, 0.000052 mol) and potassium carbonate (0.011 g, 0.000077 mol) in DMF. The reaction mixture was heated in the microwave at 100° C. for 10 min followed by 120° C. for 10 min to get full consumption of SM. The reaction mixture was concentrated in vacuo. Purification by Gilson HPLC eluting with 10→60% acetonitrile: H2O afforded the title compound as a light yellow solid. 1H NMR (400 MHz, CDCl3): δ=7.07 (t, J=4.93 Hz, 1H), 7.21 (d, J=5.05 Hz, 1H), 7.48-7.59 (m, 4H), 7.74-7.85 (m, 2H), 8.04 (d, J=8.59 Hz, 1H), 8.25 (dd, J=8.21, 1.39 Hz, 2H), 8.31 (dd, J=8.72, 1.39 Hz, 1H), 8.50 (d, J=4.80 Hz, 2H). MS(ES+): m/z 465.98 (100)[MH+]. HPLC: tR=2.75 min (Open Lynx polar—5 min).
