Benzimidazole-4,7-diones 3a and 3b were synthesized and submitted to hetero Diels-Alder reactions with azadienes 4 and 5 to afford imidazo[4,5-g]quinoline- 4,9-diones 6-9. The structure of the latter was assigned by X-ray diffraction, 1H NMR NO
An improved methodology for the preparation of 4,7-dimethoxy-1H- benzimidazole, a key intermediate in the synthesis of 1-alkyl-1H-benzimidazole- 4,7-diones

We reported an optimized process for the preparation of key intermediate, 4,7-dimethoxy-1H-benzimidazole, from commercially available 1,4-dimethoxybenzene (Overall yield 52%). We successfully applied this methodology to an improved synthesis of 1-benzyl-1
