Heterocyclic aldehydes (A) reacted with alkyl aryl ketones (B) to give the corresponding 1,3-diaryl-2-propen-1-ones (Ia-1). Condensation of these chalcones with guanidine produced the corresponding 2-amino-4,6-diarylpyrimidines (IIa-1). The structure of all products was substantiated by chemical and spectroscopic methods.
