الإجراء التجريبي

1-([1,1'-Biphenyl]-2-ylmethyl)-2-ethyl-4-hydroxy-1H-indole (911 mg, 2.8 mmol) was alkylated by treating with 0.26 mL (2.8 mmol) of methyl bromoacetate and 111 mg (2.8 mmol) of 60% NaH/mineral oil in DMF as described in Example 1, Part E. The product was purified by chromatography over silica gel eluting with 20% EtOAc/hexane, to give 655 mg (59% yield) of [[1-([1,1'-biphenyl]-2-ylmethyl)-2-ethyl-1H-indol-4-yl]oxy]acetic acid methyl ester.
