Procedure

1.75 g (10 mmol) of 2-chloro-4,6-dimethoxypyrimidine, 1.02 g (10 mmol) of α-hydroxy-γ-butyrolactone and 0.26 g (2.5 mmol) of sodium methanesulfinate were heated in the presence of 2.07 g (15.0 mmol) of potassium carbonate in 10 ml of N,N-dimethylformamide to 120° C. with stirring. After 2 hours, the solvent was removed in a rotary evaporator at 70° C./20 mbar. The residue was taken up in 30 ml of water and 30 ml of dichloromethane. After the organic phase had been separated off, the aqueous phase was again extracted with 20 ml of dichloromethane. The combined organic phases was washed with water, dried over magnesium sulfate and evaporated. The title product was obtained in a yield of 0.43 g (15.5 percent of theory) in the form of a pale brown oil (GC content 94 percent). Other data concerning the title compound was:
