실험 절차

A suspension of 5-iodopyrimidin-2-one (556 mg) and α-bromoacetophenone (533 mg) in triethylamine (0.5 ml) and ethanol (50 ml) was stirred at ambient temperature for 71/2 hours. The resulting solution was evaporated and the residue triturated with water. This product was purified by preparative thin-layer chromatography on silica before crystallisation from ethyl acetate to give the title pyrimidinone: yield 253 mg: m.p. 155°-157°: λmaxEtOH 238.5 nm (ε 23070), 340 nm (ε 2400), λinf 250 nm (ε 17160), 275 nm (ε 1780).
