Participants

Reaction Steps

5-(4-Aminophenyl)-3-(2-(N-tert-butoxycarbonylamino)ethoxy)isoxazole (0.1 g) was dissolved in tetrahydrofuran (I ml), and triethylamine (0.05 ml) and benzoyl chloride (0.04 ml) were successively added dropwise thereto at 5° C. under a nitrogen atmosphere, followed by stirring of the resulting mixture at room temperature for 30 minutes. The reaction mixture was poured into ice-cold water and extracted with ethyl acetate. The organic layer was washed with a saturated aqueous NaCl solution and dried over anhydrous magnesium sulfate. After filtration, the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (eluent: hexane/ethyl acetate=3/1) to obtain the title compound (0.08 g, 62%) as a colorless powder.
