실험 절차

Trifluoroacetic acid (1.4 mL) was added to a solution of 5-[2-amino-5-({4-[(4-methylpiperazin-1-yl)carbonyl]phenyl}ethynyl)pyrimidin-4-yl]-2-(5-chloro-2-methylphenyl)-1-{[2-(trimethylsilyl)ethoxy]methyl}-1H-pyrrole-3-carboxamide (0.110 g, 0.14 mmol) in dry DCM (2.8 mL) and stirred for 4 h at room temperature. After solvent removal, the residue was treated with EtOH (3 mL), 33% NH4OH (0.4 mL) and stirred for 0.5 h. The solvent was evaporated to dryness and the residue was purified by flash-chromatography on silica gel (DCM/MeOH/7N NH3 in MeOH 94/5/1) to afford the title compound as white solid (0.055 g, 71%).
