Versuchsvorschrift

6-Amino-1-isobutyl-2-thioxo-2,3-dihydro-1H-pyrimidin-4-one (1.0 g, 5.0 mmol) was suspended in 10% acetic acid (20 mL). Sodium nitrite (0.38 g, 5.5 mmol) was added and the resulting mixture was heated at 75° C. for 1 h. The reaction mixture became first pink and then purple. The purple mixture was cooled to room temperature. Then water (20 mL) was added and the purple solid was collected by filtration and washed with water to give the title compound (1.1 g, 92% yield). This solid was used in the following step without further purification.
