The cyclization of 2-cyanamino-4,6-diphenylpyridine-3-carbonitrile promoted by hydrogen halides takes place regiospecifically leading in all the cases to the 4-amino-2-halogen substituted pyridopyrimidine.This procedure completes a flexible and straightforward approach to aromatic pyridopyrimidines from acyclic precursors.
