実験手順
In a 100 ml round-bottomed flask 6-methyl-2,3-pyridinedicarboxylic acid (10 g, 55.2 mmol) and acetic anhydride (26 ml, 276 mmol) were added and heated at 100° C. under nitrogen for 5 hours. After this time the volatiles were removed under vacuum to give the title compound D32 (8.2 g) as a slightly brown solid. 1H NMR (400 MHz, DMSO-d6) δ ppm 8.41 (d, 1 H), 7.82 (d, 1 H), 2.73 (s, 3 H).
