Procedure

5,6-Diamino-1-isobutyl-2-thioxo-2,3-dihydro-1H-pyrimidin-4-one (Example 6 (c), 0.25 g, 1.2 mmol) was dissolved in formic acid (1.5 mL) and stirred at ambient temperature for 0.5 h. A pink precipitate started to form after a few minutes. Water was added and the resulting mixture stirred for 10 minutes. The pink solid was collected by filtration, washed with water and dried to yield the title compound (0.25 g, 86%). This material was used without further purification. NMR showed that the product was obtained as a mixture of two tautomers: formamide (major) and imino (minor).
