Versuchsvorschrift
A suspension of 5-bromopyrimidone hydrobromide (1.0 g, 3.9 mmol) in phosphorous oxychloride (4 mL) was heated at 90° C. for 1 h then cooled 0° C. The mixture was filtered, washed with POCl3 (2×2 mL) to furnish the title compound as a cream solid (388 mg). This compound was unstable to air and was used immediately in the next step.
