We report herein DABCO mediated one pot synthesis of 2‐(3‐benzyl‐2, 6‐dioxo‐3,6‐dihydropyrimidin‐1[2H]‐yl)‐N‐(4‐(1,3‐dioxo‐1H‐benzo[de]isoquinolin‐2[3H]‐yl) aryl) acetamides (4a‐j). The silent features of this new one pot synthesis include the shorter reaction time, high yields, simple workup, and simultaneous formation of N‐Amide and N‐benzyl bonds in the one pot. The newly synthesized compounds (4a‐j)
