실험 절차

To a 0° C. solution of (4S,5R)-5-(3-fluorophenyl)-4-methyl-1,3-oxazolidin-2-one (16.2 mg, 0.0830 mmol) in DMA (1 mL) was added NaHMDS (83 μL, 0.083 mmol). Next, a solution of methyl 2″-(bromomethyl)-4′-methoxy-2-methyl-4″-(trifluoromethyl)-1,1′:3′,1″-terphenyl-4-carboxylate (49 mg, 0.0996 mmol) in DMA (1 mL) was added via cannula. After 5 minutes, the reaction was quenched with saturated NH4Cl solution (10 mL) and diluted with EtOAc (20 ml). The aqueous layer was extracted with EtOAc (20 mL), and the combined organic extracts were washed with brine (10 mL), dried over Na2SO4, filtered, and concentrated. Purification of the residue by flash chromatography on silica gel (5 to 25% EtOAc/hexanes) afforded methyl 2″-{[(4S,5R)-5-(3-fluorophenyl)-4-methyl-2-oxo-1,3-oxazolidin-3-yl]methyl}-4′-methoxy-2-methyl-4″-(trifluoromethyl)-1,1′:3′,1″-terphenyl-4-carboxylate.
