Reaction Conditions

Reaction Steps

0.5 g (2.0 mmol) of methyl 8-difluoromethyl-5-quinolinecarboxylate was dissolved in 5 ml of ethanol, 0.43 g (10.5 mmol) of sodium hydroxide and 1 ml of water were added, and the mixture was stirred at 25° C. for 20 hours. The solvents were subsequently removed, the residue was taken up in water, washed twice with methylene chloride and adjusted to pH 1 using 10 N hydrochloric acid, and the precipitate was filtered off with suction. Drying gave 0.5 g of 8-difluoromethyl-5-quinolinecarboxylic acid (colorless crystals);
