실험 절차
5-Methyl-3-phenyl-1H-1,2,4-triazole (120 mg, 754 μmol) was dissolved in DMF (2.4 mL) and potassium carbonate (208 mg, 1.51 mmol) was added. After 20 min tert-butyl 2-bromoethylcarbamate (186 mg, 829 μmol) was added at 0-5° C. and the reaction mixture was stirred at RT for 25 h. The reaction mixture was extracted with ethyl acetate (30 mL) and washed with water (3×50 mL). The aqueous layers were back-extracted with ethyl acetate (20 mL) and the combined organic layer was dried over MgSO4 and concentrated in vacuo. The product was obtained after purification by flash chromatography (using silica gel and an ethyl acetate/heptane gradient) as white solid (237 mg, 784 μmol, 83.2%).
