الإجراء التجريبي

1-([1,1'-Biphenyl]-2-ylmethyl)-4-hydroxy-2-methyl-1H-indole (767 mg, 2.45 mmol) was alkylated by treating with 0.23 mL (2.45 mmol) of methyl bromoacetate and 98 mg (2.45 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 730 mg (77% yield) of [[1-([1,1'-biphenyl]-2-ylmethyl)-2-methyl-1H-indol-4-yl]oxy]acetic acid methyl ester, 99°-101° C.
