Under microwave irradiation, N-cyanomethylpyridinium chloride (1) reacted with chalcone (2) in the presence of ammonium acetate and acetic acid to give 2-amino-4,6-diarylpyridines (5a5c) in high yields. Compounds 5a5i can also be prepared from one-pot reactions of 1 with aromatic aldehydes (3) and substituted acetophenones (4). The structures of the products were characterized with 1H NMR, IR and HPLC-MS spectra.

Key words: chalcone, condensation, ammonium ylide, aminopyridine, microwave irradiation
