実験手順

An N,N-dimethylformamide (2 mL) solution of 7-(4-bromobutoxy)-8-propyl-4-(trifluoromethyl)-2H-chromen-2-one (30 mg, 0.074 mmol) was added with potassium carbonate (20.4 mg, 0.148 mmol) and 5-(2,3-dihydrobenzo[b][1,4]dioxin-6-yl)-5-methylimidazolidine-2,4-dione (27.4 mg, 0.111 mmol) and then stirred overnight. The reaction solution was added with water and extracted with ethyl acetate. Subsequently, the organic layer was washed with saturated saline, dried using anhydrous sodium sulfate, and concentrated under vacuum. The obtained residue was purified using thin-layer silica-gel chromatography (hexane:ethyl acetate=5:2), and the title compound (40.2 mg, 95%) was obtained as colorless oil.
