Procedure

To a mixture of tert-butyl 5-(6-acetoxy-2-[(3-phenyl)phenyl)-7-methoxyquinazolin-4-ylamino)-1H-indazole-1-carboxylate (4.30 g, 7.15 mmole) in CH3OH (300 mL) was added 28% NH4OH, and the reaction was stirred at RT for 16 h. The solution was concentrated in vacuo and the resulting solid was triturated with toluene and then hexane, followed by filtration to give tert-butyl 5-(2-[(3-phenyl)phenyl]-6-hydroxy-7-methoxyquinazolin-4-ylamino)-1H-indazole-1-carboxylate (4.40 g, 7.87 mmole). MS 560 (M+1). HPLC retention time 7.62 mins.
