실험 절차

A mixture of 767 mg (1.9 mmol) of [[3-(2-amino-1,2-dioxoethyl)-1-[(4-fluorophenyl)methyl]-2-methyl-1H-indol-4-yl]oxy]acetic acid methyl ester, 10 mL of 1N NaOH and 30 mL of MeOH was heated to maintain reflux for 0.67 hours, cooled to room temperature and stirred 1 hour. Ethyl acetate and water were added and the aqueous layer separated, made acidic to pH 2-3 with 1N HCl and the mixture extracted with ethyl acetate two times. The combined ethyl acetate extracts were dried (MgSO4) and concentrated. The remaining solid was washed with a small volume of ethyl acetate to give 593 mg (81% yield) of [[3-(2-amino-1,2-dioxoethyl)-1-[(4-fluorophenyl)methyl]-2-methyl-1H-indol-4-yl]oxy]acetic acid, mp, 244-247° C.
