Reaction Steps

A mixture of tert-butyl 5-(6-(2-(dimethylamino)ethoxy)-7-methoxy-2-(3-nitrophenyl)quinazolin-4-ylamino)-1H-indazole-1-carboxylate (0.085 g, 0.142 mmol) and 10% Pd/C (0.100 g) in MeOH (20 ml) was hydrogenated at RT using a balloon filled with hydrogen gas. The reaction was heated at 55° C. for 1 h. The reaction mixture filtered through Celite® washing with MeOH. The filtrate was concentrated in vacuo to give tert-butyl 5-(2-(3-aminophenyl)-6-(2-(dimethylamino)ethoxy)-7-methoxyquinazolin-4-ylamino)-1H-indazole-1-carboxylate. (0.065 g, 0.128 mmol, 90%). HPLC retention time 3.42 mins.
