Reaction Steps

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) and 4-methyl-7-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-3,4-dihydro-2H-pyrido[3,2-b][1,4]oxazine (ABCR, Karlsruhe, Germany) to give the title compound as a yellow foam. (HPLC: tR 2.15 min (Method A); M+H=442 MS-ES; 1H-NMR (d6-DMSO, 400 MHz) 8.90 (s, 1H), 8.13 (s, 1H), 8.03-7.99 (m, 1H), 7.89-7.82 (m, 2H), 7.40-7.37 (m, 1H), 6.97-6.94 (m, 1H), 4.25 (t, 2H), 3.92 (s, 3H), 3.56 (s, 3H), 3.47 (t, 2H), 3.06 (s, 3H), 1.95 (s, 3H))
