Abstract
In this study, new series of 2-aryl-3-(pyrimidine-2-ylamino)imidazo[1,2-a]pyrimidine derivatives (3-secondary amine) were synthesized through one-pot reaction of aromatic ketones and 2-aminopyrimidine. These reactions were performed in the presence of I2 and DMSO. Derivatives of 3-amine compound were reacted with propargyl bromid to yield 2-phenyl-N-(prop-2-yn-1-yl)-N-(pyrimidine-2-yl) derivatives of imidazo/pyrimidine rings. Then, by Mannich reaction, one of 3-secondary amine derivatives (contains NH2 group) (1d) was reacted with different aromatic amines to form Mannich bases. All synthesized compounds were characterized via FT-IR spectroscopy, some of which were characterized by 1H-NMR spectroscopy. Other derivatives of imidazo(1,2-a)pyrimidine(1c,2c,2d,3a) were evaluated for anti-oxidant activity and one of these derivatives (2d) was tested for cytotoxic activity against breast cancer using MTT assay.
