Reaction Steps
By the method used in Part B, 3.1 g (11.7 mmol) of 2-ethyl-4-methoxy-1-(phenylmethyl)-1H-indole was O-demethylated by treating it with 48.6 mL of 1M BBr3/CH2C12 to give a material that was chromatographed on silica gel (eluted with 20% EtOAc/hexane) to give 1.58 g (54% yield) of 2-ethyl-4-hydroxy-1-(phenylmethyl)-1H-indole, mp, 86-90° C.
