Vorschrift

Using the procedure described in Example 1, Part E, 2-ethyl-4-hydroxy-1-(phenylmethyl)-1H-indole (1.56 g, 6.2 mmol) was treated with 248 mg (6.2 mmol) of 60% NaH/mineral oil and then 0.6 mL (6.2 mmol) of methyl bromoacetate. The product was purified by chromatography over silica gel eluting with 20% EtOAc/hexane, to give 1.37 g (69% yield) of [[2-ethyl-1-(phenylmethyl)-1H-indol-4-yl]oxy]acetic acid methyl ester, 89°-92° C.
