Synthesis of aryl ethers from aminoalcohols using polymer-supported triphenylphosphine

Optimum conditions for the preparation of aryl-alkyl ethers from N-protected aminoalcohols using polymer-supported triphenylphosphine have been developed. In contrast to previous literature reports, it was discovered that the progress of this reaction is greatly improved when a tertiary amine base is employed, along with minor modifications being made to the order of reagent addition.
