EXAMPLE 21 Preparation of 5-fluoro-5,6-dimethyl-6-hydroxy-5,6-dihydrouracil A suspension of 5,6-dimethyluracil (1.0g) and water (10 ml) was placed in a reaction vessel fitted with a magnetic stirrer, thermometer and gas outlet tube leading to a 10% KI trap. The suspension was heated and maintained at about 54-61C at which time F2 /N2 gas was bubbled into the suspension until fluorine was detected in the KI trap and the reaction mixture was a clear solution. The reaction mixture was allowed to cool to room temperature and 0.1 g of precipitate was collected by filtration analyzed by and identified by NMR to be 5-fluoro-5,6-dimethyl-6-hydroxy-5,6-dihydrouracil.
Statistics shows that 26305-13-5 is playing an increasingly important role. we look forward to future research findings about 2,4-Dihydroxy-5,6-dimethylpyrimidine.
