Versuchsvorschrift

5-Amino-2-hydroxy-3-methyl-6-pyridin-4-yl-3H-pyrimidin-4-one (0.46 mmol) was suspended in phosphorousoxychloride (230 mmol) at 0° C. and 2 mL ethanol was added. The reaction was heated to 100° C. overnight. The solvent was removed under vacuum. The solid was suspended in methylene chloride and collected by filtration. M+1=237.
