Abstract

Background: Looking at the previous studies on quinazolinones derivatives, only limited information’sare available on their massspectral along with the preparation of novel quinazolin-4-(3H)-one derivatives. Consolidation of Methyl-2-amino-4-Chlorobenzoate with acetic anhydride produced the cyclic compound 2-methyl 7-Chloro-1, 3-benzo-oxazine-4-one (1) which then produced 3-Amino-2-Methyl 7-Chloro quinazolin-4(3H)-ones (2) through the reaction with hydrazine hydrate. These compounds synthesized were indisputably confirmed by means of Infrared, Nuclear Magnetic Resonance (¹H and ¹³C), Gas Chromatography-Mass spectrophotometry and Elemental analysis. Discussion: The molecular ion of m/z 235 fragments to give m/z 220 by loss of –NH group. The ion of m/z 220 was broken to give m/z 206 by losing CH₂ group and fragment to m/z 177 by loss of HCO. This fragmented to m/z 162 by loss of –CH₃ group and then m/z 136 by loss of CN group. The loss of O gave m/z 120 which fragment to give m/z 93 by loss of –HCN and finally gave m/z 65 by loss of CO group. Conclusion: The electron impact ionization mass spectra of compound 2 show a weak molecular ion peak and a base peak of m/z 235 resulting from a cleavage fragmentation. Compound 2 give a characteristic fragmentation pattern. From the study of the mass spectra of compound 2, it was found that the molecular ion had fragmented to the m/z 220. The final fragmentation led to ion of m/z 93 and ion of mass m/z 65, respectively.
