By the method used in Example 1, Part D, 1.16 g (3.27 mmol) of 1-([1,1'-biphenyl]-2-ylmethyl)-4-methoxy-2-propyl-1H-indole was O-demethylated by treating it with 13 mL of 1M BBr3 /CH2Cl2. The crude product was chromatographed on silica gel and eluted with 20% EtOAc/hexane to give 794 mg (71% yield) of 1-([1,1'-biphenyl]-2-ylmethyl)-4-hydroxy-2-propyl-1H-indole as an oil.
