Reaction Steps

1,1′-Carbonyldiimidazole (30.4 g ) was added to a stirred mixture of 3-carboxy-4-oxo-3,4-dihydro-1,10-phenanthroline (18 g) and DMF (400 ml). The mixture was stirred at 100° C. for 2.5 hours, and then cooled to ambient temperature. The resulting solid was filtered to give 3-(imidazol-1-ylcarbonyl)-4-oxo-3,4-dihydro-1,10-phenanthroline in 92% yield.
