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 6-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-1H-pyrrolo[3,2-b]pyridine (PepTech, Burlington, USA) to give the title compound as a white solid.
