Versuchsvorschrift

A mixture of 162 mg (0.35 mmol) of [3-[[3-(2-amino-2-oxoethyl)-2-ethyl-1-(phenylmethyl)-1H-indol-5-yl]oxy]propyl]phosphonic acid dimethyl ester and 5 mL of 1N NaOH in 10 mL of MeOH was heated to maintain reflux for 5 hours, diluted with water and extracted with ethyl acetate. The aqueous layer was made acidic to pH 2-3 with 1N HCl and extracted with ethyl acetate. The ethyl acetate solution was washed with brine, dried (MgSO4) and concentrated at reduced pressure to give 120 mg (77% yield) of [3-[[3-(2-amino-2-oxoethyl)-2-ethyl-1-(phenylmethyl)-1H-indol-5-yl]oxy]propyl]phosphonic acid monomethyl ester.
