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.

A four-step synthesis to aryl etherderivatives, three of which utilize polymer-supported reagents, has been developed. Supported triphenylphosphine was successfully utilized in two distinct synthetic processes in the first step, whilst supported base and ionic and covalent scavengers were employed to complete the synthesis and purification of the target compounds.
