実験手順

To a solution of benzyl{2-[3,5-bis(trifluoromethyl)phenyl]-2-hydroxy-1,1-dimethylethyl}carbamate (65 mg, 0.149 mmol) in THF (1.5 mL) was added NaH (13 mg, 0.542 mmol) and methyl 2″-(bromomethyl)-4′-methoxy-2-methyl-4″-(trifluoromethyl)-1,1′:3′,1″-terphenyl-4-carboxylate (91.1 mg, 0.185 mmol). The reaction was stirred for 72 hours, and then additional NaH (36.2 mg, 1.51 mmol) was added. After 6 more hours at room temperature, the reaction was quenched with saturated NH4C1 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 reverse-phase chromatography (C-18, 10 to 95% MeCN/water with 0.1% TFA) afforded 2″-({5-[3,5-bis(trifluoromethyl)phenyl]-4,4-dimethyl-2-oxo-1,3-oxazolidin-3-yl}methyl)-4′-methoxy-2-methyl-4″-(trifluoromethyl)-1,1′:3′,1″-terphenyl-4-carboxylic acid.
