Synthesis of some novel 7-(1H-benzimidazol-2-ylazo)-1,3-dimethyl-6,8-disubstituted-1,5-dihydro pyrimido[4,5-b] [1,4] diazepine-2,4-diones as potential antianxiety agents
摘要:
An efficient and mild method for the synthesis of some novel 7-(1H-benzimidazol-2-ylazo)-1,3-dimethyl-6,8-disubstituted-1H-pyrimido [4,5-b][1,4]diazepine-2,4-diones in water has been developed. This method is a good option to obtain the title compounds in quantitative yields in a simple and inexpensive manner. Further, the NH of the title compounds was replaced by various substituents in an ionic liquid, [bmim]PF6, a recyclable and environmentally benign solvent. The synthesized compounds were characterized by analytical and spectral (IR. H-1-NMR, C-13-NMR and FAB mass) data and have been screened for their anti-anxiety activity in mice.
