PROCEDURE

实验过程

A mixture of 4-chloro-2-[(3-phenyl)phenyl]-7-methoxyquinazolin-6-yl acetate (4.00 g, 9.88 mmole), tert-butyl 5-amino-1H-indazole-1-carboxylate (2.42 g, 10.37 mmole) in iso-propanol (130 mL) was stirred at 95° C. for 2 h. The reaction was cooled to RT and the crude product was filtered and then washed with ether, iso-propanol, and hexane and dried under vacuum to give tert-butyl 5-(6-acetoxy-2-[(3-phenyl)phenyl)-7-methoxyquinazolin-4-ylamino)-1H-indazole-1-carboxylate (4.33 g, 7.20 mmole, 77% over two steps). MS 602 (M+1). HPLC retention time 6.47 mins.
