A mixture 5,6-dihydrouracil (4.45 g, 39.028 mmol), 3-{[tert-butyl(dimethyl)silyl]oxy}propan-1-ol (3 mL, 13.01 mmol) and Cs2CO3 (16.95 g, 52.04 mmol) in dry DMF (120 mL) was stirred at room temperature overnight. The reaction mixture was partitioned between ethyl acetate and water. Combined organic extracts were washed with water and brine, dried over Na2SO4 and the solvent evaporated in vacuo. Purified by chromatography on silica gel using ethyl acetate and hexane (60:40) to give the title compound.
