실험 절차
A mixture of 4-chloro-7-methoxy-6-(2-methoxyethoxy)-2-(3-nitrophenyl)quinazoline (0.500 g, 1.28 mmol) and 5-amino-1H-indazole-1-carboxylate (0.314 g, 1.34 mmol) in iso-propanol (30 mL) was heated at 95° C. for 30 minutes and at 95° C. for 8 h. The mixture was allowed to cool to RT and the solid was collected via filtration. The cake was washed with iso-propanol and Et2O, triturated with CH2Cl2 and EtOAc and dried in vacuo to give tert-Butyl 5-(7-methoxy-6-(2-methoxyethoxy)-2-(3-nitrophenyl)quinazolin-4-ylamino)-1H-indazole-1-carboxylate (0.560 g, 0.955 mmol, 71%). MS 587 (M+1). HPLC retention time 7.21 mins.
