Reaction Steps

The title compound was synthesized in a similar manner as described for Example 1.1 using 8-bromo-1-(1-isopropyl-3-methyl-1H-pyrazol-4-yl)-3-methyl-1,3-dihydro-imidazo[4,5-c]quinolin-2-one (Intermediate G, 50 mg, 0.125 mmol) and 2-dimethylamino-pyrimidine-5-boronic acid pinacol ester (Frontier Scientific, Logan, USA, 38 mg, 0.153 mmol) to give the title compound as a white solid. (HPLC: tR 2.68 min (Method A); M+H=443 MS-ES; 1H-NMR (d6-DMSO, 400 MHz) 8.93 (s, 1H), 8.46 (s, 2H), 8.20 (s, 1H), 8.09-8.02 (m, 1H), 7.91-7.84 (m, 1H), 7.38 (s, 1H), 4.60-4.51 (m, 1H), 3.56 (s, 3H), 3.13 (s, 6H), 1.97 (s, 3H), 1.49-1.44 (m, 6H))
