実験手順

The title compound was synthesized in a similar manner as described for Example 1.1 using 8-bromo-1-(1,3-dimethyl-1H-pyrazol-4-yl)-3-methyl-1,3-dihydro-imidazo[4,5-c]quinolin-2-one (Intermediate A, 40 mg, 0.107 mmol) and 2,2-difluorobenzo[1,3]dioxole-4-boronic acid (Apollo, Cheshire, United Kingdom, 26 mg, 0.130 mmol) to give the title compound as a white solid. (HPLC: tR 2.95 min (Method A); M+H=450 MS-ES; 1H-NMR (d6-DMSO, 400 MHz) 9.01 (s, 1H), 8.18-8.13 (m, 1H), 8.08 (s, 1H), 7.97-7.91 (m, 1H), 7.88-7.84 (m, 1H), 7.441-7.38 (m, 2H), 7.36-7.29 (m, 1H), 3.85 (s, 3H), 3.58 (s, 3H), 1.94 (s, 3H))
