Reaction Steps

To an AcOEt (10 mL) solution of tert-butyl {4-[(5-aminopyridin-2-yl)oxy]phenyl}methylcarbamate (0.50 g) and triethylamine (0.32 g) was added 2,3,4-trifluorobenzoyl chloride (0.37 g) at 0° C. The mixture was stirred at room temperature for 1 hour. The mixture was poured into water and extracted with AcOEt. The organic layer was washed with water, saturated aqueous NaCl, dried over anhydrous Na2SO4 and concentrated under reduced pressure. The residue was dissolved in CH2Cl2 (10 mL), then added TFA (3 mL). After stirring at room temperature for 2 hours, the mixture was poured into saturated aqueous NaHCO3 and extracted with AcOEt. The organic layer was washed with water, saturated aqueous NaCl, dried over anhydrous Na2SO4 and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (n-hexane/AcOEt=2/1) to afford the title compound (0.55 g) as a white solid.
