Pd(Ph3P)4 (2.074 g, 1.79 mmol) was added to a mixture of 8-bromo-1-(cis-3-methoxycyclobutyl)-3-methylimidazo[4,5-c]quinolin-2-one (13 g, 35.89 mmol), N,N-dimethyl-3-[5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridin-2-yl]oxypropan-1-amine (13.15 g, 43.07 mmol) and cesium carbonate (23.39 g, 71.78 mmol) in 1,4-dioxane (200 mL) and water (40 mL) under nitrogen. The resulting mixture was stirred at 90° C. for 3 h before being allowed to cool. The reaction mixture was concentrated and diluted with EtOAc (750 mL), and washed sequentially with water (2×150 mL), and sat. brine (150 mL). The organic layer was dried over Na2SO4, filtered and evaporated to afford crude product. The crude product was purified by FCC, elation gradient 0 to 10% MeOH in DCM, to afford the desired material (12.50 g, 75%) as a white solid.
