Reaction Steps
[3-[[3-(2-amino-2-oxoethyl)-2-ethyl-1-(phenylmethyl)-1H-indol-5-yl]oxy]propyl]phosphonic acid dimethyl ester (150 mg, 0.33 mmol) and 0.35 mL (2.6 mmol) of trimethylsilyl bromide in 2 mL of methylene chloride was stirred for 16 hours, 5 mL of MeOH added, stirred 1.0 hour and concentrated at reduced pressure. The residue was crystallized from EtOAc/MeCN/HOAc/water to give 138 mg (97% yield) of [3-[[3-(2-amino-2-oxoethyl)-2-ethyl-1-(phenylmethyl)-1H-indol-5-yl]oxy]propyl]phosphonic acid, mp, 194-196° C.
