The syntheses of 2-(2-nitrophenyl)-1-benzoyl-1H-benzimidazole derivatives 5-9 and their reduction to the corresponding 2-benzimidazoylbenzamides 10-13 are described. Compounds 10-13 were cleanly and efficiently converted to the corresponding 6-arylbenzimidazo[1,2-c]quinazolines 17-20 by microwave activation using SiO2-MnO2 as solid inorganic support.
描述了2-(2-硝基苯基)-1-苯甲酰基-1H-苯并咪唑衍生物5-9的合成及其还原成相应的2-苯并咪唑酰基苯甲酰胺10-13。使用SiO2-MnO2作为固体无机载体,通过微波活化,将化合物10-13干净有效地转化为相应的6-芳基苯并咪唑[1,2-c]喹唑啉17-20。
