Reaction Steps

To (4S,5R)-5-[3,5-bis(trifluoromethyl)phenyl]-3-[(3-bromo-6-chloropyridin-2-yl)methyl]-4-methyl-1,3-oxazolidin-2-one (INTERMEDIATE 32) (460 mg, 0.889 mmol) in THF (10 mL) was added potassium carbonate (2 M in water, 1.3 mL, 2.67 mmol), 1,1′-bis(diphenylphosphino)ferrocene-palladium(II)dichloride dichloromethane complex (57.9 mg, 0.089 mmol) and (4-fluoro-5-isopropyl-2-methoxyphenyl)boronic acid (INTERMEDIATE 59) (283 mg, 1.33 mmol). The reaction was degassed with nitrogen and heated at 32° C. for 16 hr. The reaction was then poured into brine and extracted with ethyl acetate (2×10 mL). The combined extracts were dried over sodium sulfate, filtered, and concentrated. The residue was purified via flash chromatography on silica gel to afford (4S,5R)-5-[3,5-bis(trifluoromethyl)phenyl]-3-({6-chloro-3-[4-fluoro-2-methoxy-5-(propan-2-yl)phenyl]pyridin-2-yl}methyl)-4-methyl-1,3-oxazolidin-2-one (419.4 mg, 0.693 mmol) LCMS calc.=605.1. found=605.1.
