Reaction Steps

A mixture of 8-ethoxycarbonyl-3-nitro-4-oxo-3,4-dihydro-1,10-phenanthroline (0.55 g) and 2M sodium hydroxide solution (5 ml) was stirred at reflux for 2 hours. The hot suspension was neutralised with glacial acetic acid, cooled and diluted with water. The mixture was filtered and washed with water to give 8-carboxy-3-nitro-4-oxo-3,4-dihydro-1,10-phenanthroline in 98% yield.
