Versuchsvorschrift

A suspension of 5-chloropyrimidin-2-one (399 mg). and 2-bromo-4'-methylsulphinylacetophenone (784 mg) in triethylamine (1 ml) and ethanol (20 ml) was stirred at ambient temperature for one hour, when the resulting suspension was chilled in ice. The collected solid was crystallised from ethanol to give the title pyrimidinone (509 mg,); m.p. 219°-220°; λmaxEtOH 233.5 nm (ε 17920), 332 nm (ε 2060), λinf 266 nm (ε 9280).
