The title compound was prepared in a manner similar to that described in Example 6 by adding a solution of 4-acetyl-1-(chloromethoxy)benzene [see Preparation 7] (2.2 mmol) in dichloromethane (5 ml) to a solution of 5-chloropyrimidin-2-one hydrochloride (2.2 mmol) and triethylamine (4.4 mmol) in dichloromethane (20 ml). The product was the desired N-alkylated isomer; yield: 0.60 g (100%), m.p. 182° C. (acetone). (Found C56.38 H4.15 Calc. for C13H11ClN2O3 : C56.02; H3.99) 1H NMR (CDCl3) δ 2.50 (Me), 5.82 (CH2), 7.0 and 7.8 (H-4 and H-6, respectively, J 3 Hz). [70 eV, m/z, % rel. int.)]: 278 (7,M), 145 (31), 143 (100), 136 (18), 121 (33), 116 (22), 93 (15).
