Mode opératoire

TFA (4 mL) was added to 5-(2-[(3-phenyl)phenyl)-7-methoxy-6-(2-(4-methylpiperazin-1-yl)ethoxy)quinazolin-4-ylamino)-1H-indazole-1-carboxylate and the reaction was stirred at RT for 1.5 h. The solution was concentrated in vacuo and the crude product was triturated with ether and filtered, dried under vacuum to give 2-[(3-phenyl)phenyl)-N-(1H-indazol-5-yl)-7-methoxy-6-(2-(4-methylpiperazin-1-yl)ethoxy)quinazolin-4-amine (0.166 g, 0.283 mmole, 64% over two steps). MS 586.4 (M+1). HPLC retention time 5.06 mins.
