A different method starts with the chloromethylation of trimethyl psoralen (I) to afford (II). Subsequent condensation of chloride (II) with ethylene glycol (III) yields the hydroxyethoxy derivative (IV). This is converted to mesylate (V) upon treatment with methanesulfonyl chloride and triethylamine. Mesylate displacement by NaN3 leads to azide (VI). Finally, azide reduction to the target amine is accomplished by treatment with triphenylphosphine in moist THF.
