実験手順

A mixture of 220 mg (0.54 mmol) of [[3-(2-amino-1,2-dioxoethyl)-2-cyclopropyl-1-(phenylmethyl)-1H-indol-4-yl]oxy]acetic acid methyl ester in 5 mL of 1N NaOH and 15 mL of MeOH was heated to maintain reflux for 0.67 hours, concentrated at reduced pressure and the residue taken up in EtOAc/water. The aqueous layer was separated, made acidic with 1N HCl to pH 2-3 and EtOAc added. A precipitate formed and was separated to give 169 mg (80% yield) of [[3-(2-amino-1,2-dioxoethyl)-2-cyclopropyl-1-(phenylmethyl)-1H-indol-4-yl]oxy)acetic acid, mp, 246-249° C.
