The selective alkylation of amino groups within amine derivatives with a variety of alkyl halides was carried out using ionic liquids ([bmim] I and [bmim] PF6) in the presence of triethylamine. The reaction was found to proceed under relatively mild conditions with excellent conversions and selectivities. The ionic liquid was recycled and reused.
