1-([1,1'-Biphenyl]-2-ylmethyl)-2-cyclopropyl-4-hydroxy-1H-indole (367 mg, 1.1 mmol) was alkylated by treating with 0.1 mL (1.1 mmol) of methyl bromoacetate and 43 mg (1.1 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 265 mg (59% yield) of [[1-([1,1'-biphenyl]-2-ylmethyl)-2-cyclopropyl-1H-indol-4-yl]oxy]acetic acid methyl ester.
