The three-component reaction of malononitrile, aldehydes and thiourea/urea, is applied to the formation of
pyrimidine derivatives. The reaction occurs at best in EtOH at reflux, in the presence of high surface area and nanosized
MgO. This methodology is more convenient to compare with alternative ways because it needs shorter reaction times, allows
straightforward product isolation, and provides higher yields.

Abstract The reactions of bis(mercaptothioformylhydrazido)phthalate (2) moiety with nitrogen, sulfur and / or halogen α,β - bifunctional compounds have been studied. Structures of the products have been deduced from elemental analysis and spectral data (UV, IR, 1HNMR & mass spectra). Most of the products showed moderate activity against some bacteria.
A series of novel aminopyrimidine and diaminopyrimidine derivatives were designed and optimized to improve their potency and permeability relative to lead compound 1 (IC50 = 37.4 μM), which was discovered in a previous virtual screening. The potency of the optimized compound, 13g (IC50 = 1.4 μM), was 26-fold greater than that of 1 based on a fluorescence resonance energy transfer assay, and a parallel
