Versuchsvorschrift
To tert-butyl 5-(2-(3-(3-benzylureido)phenyl)quinazolin-4-ylamino)-1H-indazole-1-carboxylate (30 mg, 0.051 mmol) was added a solution of 1:1 TFA:CH2Cl2 (2 mL) and stirred at RT for 2 h. The reaction mixture was concentrated in vacuo and left under high vacuum for several hours. The crude product was triturated with ethyl ether to afford 14344-(1H-indazol-5-ylamino)quinazolin-2-yl)phenyl)-3-benzylurea. (25 mg, 100%)
