실험 절차

To a stirred solution of 5-[2,4-bis(benzyloxy)-6-(4-nitrophenoxy)phenyl]isoxazole-3-carboxylic acid (0.45 g, 0.84 mmol) in THF (30 mL) was added TBTU (0.300 g, 1.1 mmol). After stirring for 15 minutes at room temperature, 2-fluoroethylamine hydrochloride (0.1 g, 1 mmol) and DIPEA (0.58 mL) were subsequently added. After stirring overnight, the suspension was diluted with DCM and washed with brine, dried over Na2SO4 and evaporated to dryness. The residue was carefully chromatographed on silica gel eluting with hexane/ethyl acetate 3/1, to provide the title compound (0.46 g, 94% yield).
