실험 절차

To a solution of (S)-1-(3-bromo-phenyl)-ethylamine (1.5 g, 7.5 mmol) and 1,2,4-triazole (1.04 g, 15 mmol) in N-methylpyrrolidinone (10 mL) in a quartz tube were added potassium carbonate (2.1 g, 15 mmol) and copper (1) iodide (143 mg, 0.75 mmol). The reaction mixture was heated at 195° C. for 5 h in a Mars 5 microwave oven (600 W), cooled down to room temperature and filtered. The crude product was purified by flash chromatography (10% MeOH/89% EtOAC/1% triethylamine) to provide the title compound (504 mg, 36% yield) as a brown oil.
