Procedure
3-(2-Bromoethoxy)-5-phenylisoxazole (268 mg) was dissolved in methanol (1.0 ml), and piperidine (426 mg) was added thereto, followed by reflux of the resulting mixture for 3 hours. After the reaction mixture was added to ice-cold water (20 ml) and 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 (251 mg, 92%) as colorless crystals.
