実験手順

To a round bottom flask containing {acetyl-[3-(4′,5′-difluoro-2′-methoxy-biphenyl-4-yloxymethyl)-phenyl]-amino}-acetic acid ethyl ester (10 mg, 0.02 mmol) was added lithium hydroxide hydrate (2 mg, 0.05 mmol), tetrahydrofuran (0.5 mL) and water (0.5 mL). The reaction was stirred at room temperature overnight, diluted with ethyl acetated (25 mL) and washed with aqueous HCl (0.1 M, 25 mL) and brine (25 mL), dried over magnesium sulfate, concentrated and dried from hexanes/methylene chloride mixtures to yield {acetyl-[3-(4′,5′-difluoro-2′-methoxy-biphenyl-4-yloxymethyl)-phenyl]-amino}-acetic acid as an off white solid (12 mg, 127%) LC-MS (ES) calculated for C24H21F2NO5, 441.14; found m/z 442 [M+H]+.
