Reaction Steps
By the method used in Example 1, Part D, 1.17 g (3.9 mmol) of 4-methoxy-2-methyl-1-[(1-naphthalenyl)methyl]-1H-indole was O-demethylated by treating it with 15.6 mL of 1M BBr3/CH2Cl2 to give a material that was chromatographed on silica gel (eluted with 20% EtOAc/hexane then 50% EtOAc/hexane) to give 796 mg (71% yield) of 4-hydroxy-2-methyl-1-[(1-naphthalenyl)methyl]-1H-indole.
