실험 절차
Morpholine (871 mg) was added to 3-(2-bromoethoxy)-5-phenylisoxazole (268 mg), and the mixture was stirred at 100° C. for one hour. After ice-cold water (20 ml) was added to the reaction mixture and the resulting mixture was extracted with ether (20 ml×2), the organic layer was dried over anhydrous magnesium sulfate. After filtration, the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (eluent: ethyl acetate) to obtain the title compound (250 mg, 91%) as colorless crystals.
