Reaction Steps
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, 0.040 mmole) in DMSO (2 mL) was added pyrrolidine (0.143 g, 0.16 mL, 2.00 mmole) and the reaction was stirred at 85° C. for 4 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-(pyrrolidin-1-yl)ethoxy)quinazolin-4-amine (0.042 g, 0.075 mmole, 19%). MS 557 (M+1). HPLC retention time 5.34 mins.
