Reaction Steps

The title compound was synthesized in a similar manner as described for Example 1.1 using 2-[4-(8-bromo-3-methyl-2-oxo-2,3-dihydro-imidazo[4,5-c]quinolin-1-yl)-3-methyl-pyrazol-1-yl]-N-ethyl-N-methyl-acetamide (Intermediate P) and 2-(pyrrolidin-1-yl)pyrimidine-5-boronic acid pinacol ester (Frontier Scientific, Logan, USA, 37 mg, 0.132 mmol) to give the title compound as an off-white solid. (HPLC: tR 2.53 min (Method A); M+H=526 MS-ES; 1H-NMR (d6-DMSO, 400 MHz) cis&trans amide 8.92 (s, 1H), 8.59-8.55 (m, 2H), 8.08-8.01 (m, 2H), 7.88-7.84 (m, 1H), 7.68-7.63 (m, 1H), 5.23-5.15 (m, 1H), 5.11-5.04 (m, 1H), 3.57 (s, 3H), 3.53-3.21 (m, 6H), 3.01, 2.83 (2×s, 3H), 1.97-1.89 (m, 4H), 1.94, 1.93 (2×s, 3H), 1.17, 0.99 (2×t, 3H))
