Facile Synthesis of 1-Amino[1,3,5]triazino[1,2a]-benzimidazolo-2-one and Pyrimidino[1,2a]benzimidazolo-4-one Derivatives

N-(1-Carboethoxy-benzimidazol-2-yl) 1 reacted with different hydrazines to give [1,3,5]triazino[1,2a]benzimidazole derivatives 2. Treatment of compound 1 with tBuOK and EtONa yielded pyrimidino[1,2a]benzimidazole derivatives 3 in good yields.
