Procedure

To a mixture of tert-butyl 5-(6-(2-chloroethoxy)-2-[(3-phenyl)phenyl)-7-methoxyquinazolin-4-ylamino)-1H-indazole-1-carboxylate (0.25 g, 0.40 mmole) in DMSO (2 mL) was added morpholine (1.32 g, 1.33 mL, 15.2 mmole) and the reaction was stirred at 85° C. for 48 h. The mixture was poured onto ice-water and the crude product was filtered. The product was then dissolved in a mixture of CH2Cl2 and CH3OH and the solution was concentrated in vacuo. The residue was purified via preparative TLC (SiO2, 10% CH2Cl2/CH3OH) to give 2-[(3-phenyl)phenyl)-N-(1H-indazol-5-yl)-7-methoxy-6-(2-morpholinoethoxy)quinazolin-4-amine (0.131 g, 0.20 mmole, 50%). MS 572.2 (M+). HPLC retention time 5.27 mins.
