HCID 596196138-(5-amino-pyridin-3-yl)-1-(1,3-dimethyl-1H-pyrazol-4-yl)-3-methyl-1,3-dihydro-imidazo[4,5-c]quinolin-2-one

Procedure

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, 0.106 mmol) and 3-aminopyridine-5-boronic acid pinacol ester (Apollo Scientific, Cheshire, United Kingdom, 29 mg, 0.132 mmol) to give the title compound as a white solid. (HPLC: tR 1.99 min (Method A); M+H=386 MS-ES; 1H-NMR (d6-DMSO, 400 MHz) 8.97 (s, 1H), 8.16-8.05 (m, 2H), 7.94-7.89 (m, 1H), 7.81-7.74 (m, 2H), 7.54-7.48 (m, 1H), 7.04-6.98 (m, 1H), 5.45 (s, br, 2H), 3.91 (s, 3H), 3.57 (s, 3H), 1.95 (s, 3H))
