Example 306-Oxo-1,6-dihydro-pyridazine-4-carboxylic acid To a stirred solution of the title compound of Example 29 (4.4 g, 40 mmol) in concentrated sulphuric acid (80 mL), potassium dichromate (18 g, 61 mmol) was added in small quantities at 50-60 C. as a finely ground powder. The starting material was added to the mixture within 20 min. Stirring was continued for a further 10 min at 60 C., then the viscous green mixture was poured on crushed ice. The solid powder, which separated, was collected, washed with cold water and dried to give the title compound (4.5 g, 77%).1H NMR (400 MHz, (CD3)2SO): delta (ppm) 7.22 (s, 3H), 8.13 (s, 1H), 13.38 (s, broad, 1H).
As the paragraph descriping shows that 54709-94-3 is playing an increasingly important role.
