실험 절차

Phenylmethyl 3-[({[(1,1-dimethylethyl)oxy]carbonyl}amino)methyl]-3-hydroxyazetidine-1-carboxylate (16.5 mg, 0.05 mmol) and 10% Pd/C (8 mg) were taken into methanol (2 mL) and hydrogenated at ambient pressure over 12 hours. The catalyst was removed by filtration and the filtrate concentrated and dried in vacuo. The residue was taken into THF (1 mL) followed by addition of DIPEA (10 μL, 0.06 mmol) and 3,4-difluoro-2-[(2-fluoro-4-iodophenyl)amino]benzoyl fluoride (19.8 mg, 0.05 mmol), prepared using procedures similar to those described in Reference 1, and the solution was stirred at room temperature for 30 minutes. Concentration and purification of the residue by silica gel flash chromatography using hexanes:ethyl acetate (1:1.5) afforded 1,1-dimethylethyl {[1-({3,4-difluoro-2 [(2-fluoro-4-iodophenyl)amino]phenyl}carbonyl)-3-hydroxyazetidine-3-yl]methyl}carbamate (19 mg, 66% yield).
