EXAMPLE 2 Potassium Cinnoline-4-carboxylate (2) 5.10 g of (1) was added over 30 minutes to a vigorously stirred solution of 2.02 g of potassium carbonate in 25 ml of water, at room temperature. The resulting mixture was stirred for one hour at room temperature, then treated with charcoal, and after filtration the water was evaporated. The residue was azeotropically distilled with toluene and dried at 70 C. under reduced pressure, to give 2, as a light tan powder, m.p.: above 280 C.
21905-86-2 Cinnoline-4-carboxylic acid 89099, acinnoline compound, is more and more widely used in various.
