実験手順

A mixture of HATU (760 mg, 2.0 mmol), crude 1-benzyl-2-oxo-1,2-dihydropyrazolo[1,5-a]pyridine-3-carboxylic acid (268 mg, 1.0 mmol), 5-(7-methoxyquinolin-4-yloxy)pyridin-2-amine (220 mg, 1.0 mmol), and triethylamine (2000 μl, 14 mmol) in DMF (3 mL) plus CHCL3 (3 mL) was stirred at 60° C. for 4 days. Then, the mixture was diluted with EtOAc (10 mL) and H2O (5 mL). The organic layer was washed with NaOH (1 N), H2O, NaHCO3, and dried over Na2SO4. The organic residue was purified on silica and further purified by trituration with EtOAc in ether (5%), resulting a light green powder. Calc'd for C30H23N5O4: 517; MS (ESI pos. ion) m/z: 518
