To a solution of 2-bromo-6-chloro-4-(1-cyclobutylethoxy)-3-((trans-4-methylcyclohexyl)methyl)-3H-imidazo[4,5-c]pyridine (1.5 g, 3.40 mmol) in DMSO (15 mL), in a microwave tube was added (R)-3-phenylmorpholine (797 mg, 4.77 mmol) and cesium fluoride (3.6 g, 23.8 mmol). The reaction was heated at 125° C. in a microwave for 45 mins. The reaction was then diluted with water (50 mL) and extracted with ethyl acetate (2×30 mL). The combined organic extracts were washed with water (20 mL) and brine (20 mL), dried over anhydrous Na2SO4, filtered, and concentrated. The residue was purified by silica gel chromatography (eluting with 8-10% EtOAc/petroleum ether) to yield (3R)-4-(6-chloro-4-(1-cyclobutylethoxy)-3-((trans-4-methylcyclohexyl)methyl)-3H-imidazo[4,5-c]pyridin-2-yl)-3-phenylmorpholine. MS ES/APCI calc'd. for C30H39ClN4O2 [M+H]+ 523. found 523.
