Reaction Steps

Methyl 3′-[2-({(4S,5R)-5-[3,5-bis(trifluoromethyl)phenyl]-4-methyl-2-oxo-1,3-oxazolidin-3-yl}methyl)-6-isopropenylpyridin-3-yl]-4′-methoxy-2-methylbiphenyl-4-carboxylate (131 mg, 0.189 mmol) and a catalytic amount of palladium on carbon and CH3OH (5 mL) were stirred vigorously under a balloon atmosphere of hydrogen for 1 h and 20 min at 20° C. The reaction mixture was filtered then the filtrate was concentrated in vacuo to afford methyl 3′-[2-({(4S,5R)-5-[3,5-bis(trifluoromethyl)phenyl]-4-methyl-2-oxo-1,3-oxazolidin-3-yl}methyl)-6-isopropylpyridin-3-yl]-4′-methoxy-2-methylbiphenyl-4-carboxylate, as a light yellow glass. LCMS calc.=700.24; found=701.29 (M+1).
