Participants

Reaction Steps

A solution of 100 mg (0.245 mmol) of 2-[[3-(2-amino-2-oxoethyl)-2-methyl-1-(phenylmethyl)-1H-indol-4-yl]oxy]acetic acid methyl ester and 2 mL of 1N NaOH in 5 mL of EtOH was stirred for 2.0 hours, diluted with water and extracted with EtOAc. The aqueous layer was made acidic to pH 6 with 1N HCl and extracted with EtOAc, the EtOAc dried (MgSO4), and concentrated at reduced pressure. The residue was crystallized from MeOH to give 54 mg (57% yield) of 2-[[3-(2-amino-2-oxoethyl)-2-methyl-1-(phenylmethyl)-1H-indol-4-yl]oxy]acetic acid, mp, 225°-227° C.
