A solution of chloromethyl 2-methylbenzyl ether (see Preparation 3a and 3b) (10 mmol) in dichloromethane (20 ml) was added dropwise with stirring to a solution of 5-chloropyrimidin-2-one hydrochloride (10 mmol) and triethylamine (20 mmol) in dichloromethane (80 ml). The reaction mixture was stirred for 2 hours at room temperature. It was then washed with water and the dried (MgSO4) solution evaporated to yield a crude mixture (2.55 g, 96%) which was purified by trituration with ether. The yield of the title compound was 1.33 g (50%), m.p. 88° C. 1H NMR (CDCl3): δ2.26 (Me), 4.63 (CH2 -Ph), 5.30 (CH2O), 7.00 (Ph), 7.60 and 8.37 (H-4, H-6, J 4 Hz). IR(KBr): 1660 cm-1 (CO).
