実験手順
3-(4-Fluorophenyl)-1H-1,2,4-triazole (CAS [95728-10-2], 200 mg, 0.9 mmol) was dissolved in a mixture of dimethylformamide and water (5.5 ml; v/v=10:1) and (S)-tert-butyl 2-(4-bromophenyl)morpholine-4-carboxylate (368 mg, 1.08 mmol), cesium carbonate (1.46 g, 4.48 mmol), copper(I)-iodide (5.1 mg, 0.027 mmol) and 8-hydroxyquinoline (4 mg, 0.027 mmol) were added successively. The glass was closed and the reaction mixture was allowed to stir at 150° C. for 48 h. According to TLC, the reaction was finished. After cooling, water and ethyl acetate were added. The organic layer was dried over MgSO4 and evaporated. The crude material was purified by flash chromatography (silica gel, gradient heptane/ethyl acetate), off-white solid (205 mg, 54%), MS (ISP): 425.2 ([M+H]+).
