실험 절차

A mixture of 4,6-dimethyl-5-bromopyrimidin-2-one (4.7 mmol) and triethylamine (4.7 mmol) in dichloromethane (60 ml) was heated at 40° C. for dissolution. The solution was then cooled to room temperature and (chloromethoxy)benzene [see Preparation 2] (4.7 mmol) in dichloromethane (15 ml) was added. The resultant mixture was stirred at room temperature for 11/2 h, the solvent distilled off, the mixture triturated with water, the remaining solid extracted with chloroform, the dried (MgSO4) chloroform solution evaporated, the residue triturated with a little ether, the residue redissolved in chloroform and the solution chromatographed on a column of alumina, activity III, using chloroform, Yield 0,35 g (24%), m.p. 120° C.
