実験手順
8-chloro-7-(2-propen-1-yl)-3,7-dihydro-1H-purine-2,6-dione (1.5 g, 6.64 mmol), sodium carbonate (844 mg, 7.9 mmol) and 4-bromo-1,1,1-trifluorobutane (1.39 g, 7.3 mmol) were stirred in dimethylformamide (25 ml, dry) for seven days. The reaction mixture was partitioned between ethyl acetate and water. The organic phase was separated and washed with hydrochloric acid (2N), brine, dried (MgSO4) and then evaporated to dryness. The crude product was triturated with ether and the solid collected by filtration to afford 8-chloro-7-(2-propen-1-yl)-3-(4,4,4-trifluorobutyl)-3,7-dihydro-1H-purine-2,6-dione as a white solid (1.23 g, 57%). m/z 337 [MH+].
