Procedure

To a solution of (8-(benzyloxy)-5-((1R)-2-bromo-1-{[tert-butyl(dimethyl)silyl]oxy}ethyl)quinolin-2(1H)-one (V) (4.80 g, 9.83 mmol) and 6-(2,2-Difluoro-2-phenylethoxy)hexyl]amine (IV) (3.04 g, 11.8 mmol) in dimethylsulfoxide (13.5 mL) was added sodium bicarbonate (2.49 g, 29.4 mmol) and sodium iodide (2.22 g, 14.8 mmol). The mixture was heated at 140° C. for 2 hours. After cooling, the reaction was diluted with water (40 mL) and extracted with diethyl ether (2×20 mL). The combined organic extracts were washed with water (2×10 mL) and brine (20 mL), dried (Na2SO4), and the solvent removed under reduced pressure. The title compound was obtained (6.40 g, 98%) as oil.
