Procedure

To a solution of tert-butyl 5-(6-hydroxy-7-methoxy-2-(3-(nicotinamido)-phenyl)quinazolin-4-ylamino)-1H-indazole-1-carboxylate (0.108 g, 0.179 mmol), 1-bromo-2-methoxyethane (0.054 g, 0.389 mmol) and K2CO3 (0.052 g, 0.449 mmol) in DMF (2 mL) were heated at 85° C. for 3 h. The mixture was allowed to cool to RT and the volatiles were removed in vacuo. The residue was purified by preparative tic (SiO2, CH2Cl2/MeOH 9:1) to give tert-butyl 5-(7-methoxy-6-(2-methoxyethoxy)-2-(3-(nicotinamido)phenyl)quinazolin-4-ylamino)-1H-indazole-1-carboxylate. The material was taken directly on to the next step. HPLC retention time 5.802 mins.
