실험 절차

1,1-Dimethylethyl {[1-({3,4-difluoro-2[(2-fluoro-4-iodophenyl)amino]phenyl}carbonyl)-3-hydroxyazetidine-3-yl]methyl}carbamate (8.0 mg, 0.014 mmol) and silver (I) oxide (12 mg, 0.05 mmol) were taken into methyl iodide (0.5 mL) and the mixture was brought to reflux for 4 hours. The suspension was then cooled to room temperature and diluted with an excess of ethyl ether then filtered. The filtrate was concentrated and purified by silica gel flash chromatography using hexanes:ethyl acetate (1:1) as eluent to give 1,1-dimethylethyl {[1-({3,4-difluoro-2[(2-fluoro-4-iodophenyl)amino]phenyl}carbonyl)-3-(methyloxy)azetidine-3-yl]methyl}carbamate (2 mg). The material was taken into TFA (0.5 mL) and allowed to stand for 5 minutes then concentrated in vacuo. The residue was azetroped twice from methanol (2 mL) and the residue dried in vacuo to afford 6-{[3-(aminomethyl)-3-(methyloxy)azetidin-1-yl]carbonyl}-2,3-difluoro-N-(2-fluoro-4-iodophenyl)aniline trifluoroacetate salt (2.3 mg, 27% yield) as an amorphous solid. MS (EI) for C18H17F3IN3O: 492 (MH+).
