HCID 596199638-(5-Amino-6-methoxy-pyridin-3-yl)-1-(3-chloro-1-methyl-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-(3-chloro-1-methyl-1H-pyrazol-4-yl)-3-methyl-1,3-dihydro-imidazo[4,5-c]quinolin-2-one (Intermediate K) and 2-methoxy-5-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-pyridin-3-ylamine (Stage 89.1.1) to give the title compound as an off-white solid. (HPLC: tR 2.45 min (Method A); M+H=436 MS-ES; 1H-NMR (d6-DMSO, 400 MHz) 8.97 (s, 1H), 8.38 (s, 1H), 8.11-8.07 (m, 1H), 7.80-7.75 (m, 1H), 7.48-7.42 (m, 2H), 7.03-7.00 (m, 1H), 5.15-5.07 (s, br, 2H), 4.00 (s, 3H), 3.90 (s, 3H), 3.59 (s, 3H))
