실험 절차

Sulphuryl chloride (3.0 mmol) in dry dichloromethane (10.0 ml) was added to 1-(4-chlorophenylsulphenyl) methyl-5-chloropyrimidin-2-one (see Example 2) (3.0 mmol) in dry dichlormethane 30.0 ml) at -30° C. for 3 mins. The mixture was stirred at -25° C. for 50 mins before cyclohexene (3.5 mmol) in dry dichloromethane (10 ml) was added. After stirring for 15 mins the mixture was filtered, evaporated and the residue washed three times with Pet. ether. Insoluble 1-chloromethyl-5-chloropyrimidin-2-one (0.45 g), 84% was used in Example 31 without further purification.
