실험 절차

3-Benzoyl-5-iodo-1H-pyrimidine-2,4-dione (Prep36, 2.5 g, 7.3 mmol), K2CO3 (1 g, 7.3 mmol) and 1-bromo-4-chloro-butane (2.10 mL, 18 mmol) were suspended in dry DMF (10 mL). After stirring the reaction at room temperature overnight, water was added and the mixture was extracted with ethyl acetate. The organic phase was dried (Na2SO4), filtered and evaporated; the crude was purified by flash chromatography with petroleum ether-ethyl acetate (7-3) to give the title compound as a white solid (3 g, 98% yield).
