Versuchsvorschrift

A suspension of ethyl 2-(2-(3-chloropropoxy)propan-2-yl)-5-hydroxy-6-oxo-1,6-dihydropyrimidine-4-carboxylate, (0.205 g, 0.64 mmol) and anhydrous potassium carbonate (0.361 g, 2.6 mmol) in anhydrous dimethylformamide (4 mL) was stirred at 60° C. for 5 hours. The reaction mixture was treated with benzyl bromide (0.122 g, 0.71 mmol) and stirred for 16 hours. Following this, 2 mL of H2O was added and the mixture stirred for an additional 24 hours. Solvent was removed by rotary evaporator and the resulting residue suspended in 0.5 N hydrochloric acid (16 mL). The crude product was extracted with ethyl acetate (2×15 mL), then dried (sodium sulfate), filtered, and concentrated to dryness by rotary evaporator to give 0.299 g (Yield>100%) of the title compound as a solid. LC/MS [M+H]+=345.21.
