A clean aqueous Krohnke reaction process has been accomplished via a one-pot procedure of 2-acetylpyridine with aromatic aldehyde and ammonium acetate under microwave irradiation or conventional heating conditions. This method is convenient, economic and environmental friendly. (c) 2006 Elsevier Ltd. All rights reserved.
