Treatment of 4-phenylbutanol (I) with PBr3 gave the corresponding bromide (II). 6-Methoxytryptamine (III) was converted to the hydrochloride salt, and then condensed with formaldehyde under Pictet-Spengler conditions to furnish the pyridoindole system (IV). Alkylation of amine (IV) with bromide (II) then gave the phenylbutyl amine (V). Finally, O-demethylation of (V) employing BBr3 yielded the title compound.
