실험 절차
A mixture of 1-(4-chloro-5-(1-ethyl-7-((4-methoxybenzyl)(methyl)amino)-2-oxo-1,2-dihydro-1,6-naphthyridin-3-yl)-2-fluorophenyl)-3-(3-((4-methylpiperazin-1-yl)methyl)phenyl)urea (78 mg, 0.112 mmol) and anisole (60 mg, 0.559 mmol) was stirred in TFA (2 mL) at RT for 2 h. The mixture was concentrated to dryness and purified via reverse-phase chromatography (MeCN/H2O with 0.1% TFA). The organics were removed under reduced pressure and the aqueous residue was treated with satd. NaHCO3. The mixture was extracted with EtOAc (2×) and the combined organics were washed with brine, dried over Na2SO4 and concentrated to dryness to afford 1-(4-chloro-5-(1-ethyl-7-(methylamino)-2-oxo-1,2-dihydro-1,6-naphthyridin-3-yl)-2-fluorophenyl)-3-(3-((4-methylpiperazin-1-yl)methyl)phenyl)urea (50 mg, 76% yield). MS (ESI) m/z: 578.2 [M+H]+.
