実験手順

A mixture of 2-(3-(benzyloxy)phenyl)-4-chloro-7-methoxy-6-(2-methoxyethoxy)quinazoline (1.55 g, 3.44 mmol) and tert-butyl 5-amino-1H-indazole-1-carboxylate (0.842 g, 3.61 mmol) in iso-propanol (100 mL) was heated at 95° C. for 2 h, upon which the an additional aliquot of tert-butyl 5-amino-1H-indazole-1-carboxylate (0.100 g, 0.43 mmol) was added. Stirring was continued at 95° C. for a further 3 h upon which a third aliquot of tert-butyl 5-amino-1H-indazole-1-carboxylate (0.050 g, 0.22 mmol) was added. Stirring was continued at 95° C. for a further 1 h upon which the mixture was allowed to cool to RT and the precipitate was collected via filtration. The solid was washed with iso-propanol and dried under vacuum to give tert-butyl 5-(2-(3-(benzyloxy)phenyl)-7-methoxy-6-(2-methoxyethoxy)quinazolin-4-ylamino)-1H-indazole-1-carboxylate (2.35 g, 3.44 mmol, 100%). MS 648 (M+1). HPLC retention time 7.79 mins.
