Versuchsvorschrift
A suspension of 3H-thieno[2,3-d]pyrimidin-4-one (7.68 g, 0.056 mol) in glacial acetic acid (75 ml) was treated with bromine (7.5 ml) and stirred at ambient temperature for 4 hours. The resulting solid was collected by filtration, washed with water and dried in vacuo to give 6-bromo-3H-thieno[2,3-d]pyrimidin-4-one as a light brown solid (11.64 g), which was used without further purification.
