the most active pyridinederivatives in this in vitro assay. The Structure-Activity-Relationship (SAR) study revealed that an aryl group at C-4 position of the central pyridine ring was preferred over the heteroaryl or alkyl moiety whereas an unsubstituted benzene ring was favored over a substituted one at the C-6 position. Similarly, an unsubstituted phenyl group appeared to be better than the substituted

The N-arylation of 2-amino-3-cyanopyridines is firstly described by using ionic copper(I) complex (Phen)(2)Cu+BF4- (phen = 1,10-phenanthroline) as an efficient catalyst. The synthetic protocol can be applied to synthesize a wide range of 2-arylamino-3-cyanopyridine products in good to excellent isolated yields. The resulted products are potentially building blocks for further preparation of biologically interesting products or useful ligands for metal catalysis.
