Reaktionsschritte

Benzyl chloride (0.01 mol) was added to a stirred mixture of the potassium salt of 5-fluoropyrimid-2-one (0.007 mol) in dimethylformamide (40 ml) and the mixture stirred at room temperature until chromatography showed the reaction to be complete. The solvent was then evaporated at reduced presure (1 mm Hg) and the residue was extracted with chloroform (100 ml). The chloroform solution was washed with aqueous 2 N NaCH (2×3 ml) and with water (3 ml) before drying (MgSO4) and evaporation; yield 50%, m.p. 163° C. (ethyl actate). (Found: C, 64.69; H, 4.49. Calc. for C11H9FN2O: C, 64.70; H, 4.44).
