3 N aqueous sodium hydroxide (5 mL, 15 mmol) was added to a solution of 6-fluoro-quinoline-3-carboxylic acid ethyl ester (2.2 g, 10 mmol) in methanol (50 mL). A heavy precipitate developed, and the mixture was diluted with an additional 50 mL of methanol to facilitate stirring. The mixture was stirred for 3 hours, then neutralized with of 1N hydrochloric acid (15 mL). The methanol was evaporated in vacuo, and the slurry diluted with water. The product was collected by filtration and washed with water, to give the product, 1.76 g (92%) as a colorless solid. MS: m/z 192.1 (MH+).
