Abstract: Novel 5,5-dimethyl-2,2-di(pyridin-2-yl)hexahydropyrimidine was synthesized in good yield by a one-pot condensation reaction of 2,2-dimethylpropane-1,3-diamine with di(pyridin-2-yl)methanoneusing dichloromethane as solvent at room temperature. The structure of the synthesized compound was assigned on the basis of its elemental analysis, UV-visible, 1H-NMR, 13C-NMR, IR, and mass spectral data.

Dr. Iz-Addin noted that the idea of the Bioequivalence Unit began in 1994 with the establishment of the Faculty of Pharmacy. Since that time, An-Najah has made considerable progress in the field of pharmacy, conducting a number of studies throughout the 1990s and founding The Drug Control and Biological and Chemical Analysis Center in 1999. Since its establishment, the Center has been working in cooperation with the Ministry of Health to offer drug analysis services. In order to build on its pharmaceutical research and services, the University launched a feasibility study in 2009, examining the possibility of founding a bioequivalence unit. Following the results of the study, in 2012, the University presented a formal application to the Ministry of Health to receive the first accreditation for a unit focusing on bioequivalence studies.
