実験手順
To a solution of 6-cyano-2-methyl-5-(pentan-3-ylamino)nicotinate (0.543 g, 1.97 mmol) in DMSO (10 ml) were added 50% aqueous hydrogen peroxide (0.2441 g, 3.55 mmol) and potassium carbonate (0.068 g, 0.49 mmol) at 10° C. The reaction mixture was stirred at room temperature for two hours then a solution of potassium hydroxide (0.22 g, 3.94 mmol) in water (2 ml) and methanol (10 ml) were added to above reaction mixture. After being stirred for another two hours at 45° C., the reaction mixture was cooled to room temperature and neutralized to PH 7. 6-(Aminocarbonyl)-2-methyl-5-(pentan-3-ylamino)nicotinic acid (0.453 g, 87%) was obtained by filtration and drying. 1HNMR (400 MHz, MeOH-D4): 7.62 (s, 1H), 3.35 (m, 1H), 2.60 (s, 3H), 1.65 (m, 2H), 1.52 (m, 2H), 0.95 (t, J=7.20 Hz, 6H). MS (EI) for C13H20N3O3: 267.2 (MH+).
