실험 절차

To a solution of ethyl 6-chloro-4-(5-isopropyl-6-methoxypyridin-2-ylamino)pyridazine-3-carboxylate (500 mg, 1.43 mmol) was added 7N ammonia in MeOH (20.5 mL, 143 mmol). The mixture was stirred at 40° C. for 18 h, after which the solvent was removed to give 6-chloro-4-(5-isopropyl-6-methoxy-pyridin-2-ylamino)-pyridazine-3-carboxylic acid amide (450 mg, 98%) as an off-white solid. 1H NMR (400 MHz, CHLOROFORM-d6) 8 ppm 11.47 (s, 1H), 9.10 (s, 1H), 8.17 (s, 1H), 7.48 (d, J=8.0 Hz, 1H), 6.53 (d, J=7.7 Hz, 1H), 5.71 (s, 1H), 4.04 (s, 3H), 3.18 (m, 1H), 1.23 (d, J=7.1 Hz, 6H).
