Reaction Steps

A suspension of 8.64 g (31.17 mmol) of 6,7-dimethoxy-2,3-quinolinedicarboxylic acid in 125 ml of aqueous hydrogen iodide solution (57%) was refluxed for 3 hours. After cooling, the precipitate was filtered off by suction, washed with water and dried in vacuo to give 4.7 g (60.5%) of desired acid with melting point >300° C.
