1,4-Dihydro-1-ethyl-6-iodo-4-oxo-quinoline-3-carboxylic acid ethyl ester (7.5 g, 0.02 mol) was suspended in THF (75 mL), NaOH (2 equiv.) solution in water (75 mL) was added and the mixture was stirred at 80° C. for 24 hours. After THF was evaporated, the solution was acidified to pH 5 using HCl. The obtained precipitate was filtrated off and dried under reduced pressure yielding the title compound (7.3 g).
