Procedure
Potassium carbonate (0.766 g) was added to a stirred solution of 2-mercaptopyrimidine (0.622 g) in acetone (10 cm3) at ambient temperature. 2-(2-Bromoethyl)-1,3-dioxolane (1 g) was added to the resulting mixture and the reaction heated under reflux for 3.5 hours. The reaction mixture was left to cool overnight, then poured into water and extracted with diethyl ether. The organic phase was dried with magnesium sulfate and evaporated under reduced pressure to give a yellow oil. This material was used in step 2 without further purification. M+ =212; 1H NMR (CDCl3): δ2.25 (2H,m); 3.25(2H,t); 3.90 (2H,m); 4.00 (2H,m); 5.05 (1H,t); 6.96 (1H,t); 8.52 (2H,d).
