Monoalkylation of primary amines using amine hydrobromides and alkyl bromides has been carried out. Under controlled reaction conditions the reactant primary amine was selectively deprotonated and made available for reaction, while the newly generated secondary amine remained protonated, and did not participate in alkylation further. Reaction was carried out under mild reaction conditions and was applicable to a wide range of primary amines and alkyl bromides.

A ketoester resin was developed as the basis for a selective scavenger for primaryamines in the presence of secondaryamines. The utility of the scavenger was demonstrated with a range of reductive amination chemistries with both mono- and diamines. The resin's specificity is based on the removal of the primaryamines via their enamines.
