실험 절차

A mixture of ethyl 3-(2-(4-fluoro-1H-indol-2-yl)-6-(2-(4-fluorophenyl)-3-(methylcarbamoyl)-6-(N-methylmethylsulfonamido)benzofuran-5-yl)pyridin-3-yl)propanoate (91 mg, 0.133 mmol) and lithium hydroxide monohydrate (27.8 mg, 0.663 mmol) were suspended in THF (0.53 mL), MeOH (0.27 mL), and H2O (0.2 mL). The resultant mixture was stirred at ambient temperature overnight then cooled in an ice bath and acidified to pH 2 with 1 N HCl. The mixture was then diluted with EtOAc and H2O, separated into layers and the aqueous layer extracted with EtOAc (2×). The combined organic layers were washed with brine (4×) until last brine wash was pH 7 then were dried over MgSO4, filtered, and concentrated in vacuo. The resulting product was azeotroped from CH3CN (4×) and used as a tan solid without further purification. MS (M+H)+: 659.
