실험 절차

A solution of 4-bromo-3,5-dimethylpyridine (1.16 g, 6.21 mmol) and degassed toluene (5 mL) was added to a mixture of 4-amino-8-(cyclopropylmethoxy)-7-methoxyquinolin-2(1H)-one (1.94 g, 7.45 mmol, intermediate for Example 3), Pd2(dba)3, (0.28 g, 0.31 mmol), 2,2-dicyclohexylphosphorane triisopropylbiphenyl (0.59 g, 1.24 mmol), sodium tert-butoxide (1.20 g, 12.4 mmol), and degassed toluene (20 mL) under N2. The mixture was heated at 110° C. for 2 h, allowed to cool to rt, sonicated until the solids broke up, and then filtered through Celite with EtOAc (500 mL). The filtrate was concentrated, purified by silica gel chromatography (0→8% MeOH/CH2Cl2), and then repurified by reverse-phase HPLC (25→100% MeCN/H2O) to give 8-(cyclopropylmethoxy)-4-(3,5-dimethylpyridin-4-ylamino)-7-methoxyquinolin-2(1H)-one: 1H NMR (400 MHz, DMSO-d6): δ 9.64 (s, 1H), 8.43 (s, 1H), 8.42 (s, 2H), 7.89 (d, 1H), 7.03 (d, 1H), 4.54 (s, 1H), 3.91 (s, 3H), 3.85 (d, 2H), 2.15 (s, 6H), 1.28 (m, 1H), 0.47 (m, 2H), 0.28 (m, 2H); MS (ESI): 365.8.
