A novel multicomponent reaction involving a direct C–N esterification/arylation has
been developed. This catalyst-free process was conducted with cyclic tertiary amines
via a facile C–N cleavage to provide the alkyl group and nitrogen source. The operationally
simple method to rapidly combine cyclic tertiary amines, haloazaarenes and carboxylic
acids (or anhydrides) affords an efficient access to aromatic aminoalkyl esters, potential
drug-like products, in good to excellent yields.
