cyclic 1,3‐diketones, dimethylformamide dimethylacetal (DMFDMA) and 2‐(1H‐benzo[d]imidaz‐2‐yl)acetonitrile was found to be a highly selective process leading to 4‐oxo‐1,2,3,4‐tetrahydrobenzo[4,5]imidazo[1,2‐a]quinolin‐6‐yl cyanides. Optimized reaction conditions using water as solvent at room temperature or under microwave heating allowed high yields of the target products required no additional purification
