A mixture of 5-(thiophen-2-yl)pyrimidine-2,4(1H,3H)-dione (Prep22, 1 g, 5.15 mmol), 1-bromo-3-chloropropane (0.81 g, 5.15 mmol) and potassium carbonate (0.71 g, 5.15 mmol) in DMF (10 ml) was stirred at room temperature for 7 hours, then the mixture was diluted with water and extracted with ethyl acetate. Organic phase was evaporated and the crude was purified by a FC (eluent P:E=3:1, 1:1) to afford the title compound (300 mg, y=21%)
