実験手順

5,5-Dimethyl-3-(4-trifluoromethylsulfanylphenyl)imidazolidine-2,4-dione 3 (1 g, 3.29 mmol) is dissolved in 10 ml of DMF, 1.36 g of K2CO3 (3 eq, 9.87 mmol) and 909 mg of 2-chloro-4-chloromethylpyridine (3.95 mmol, 1.2 eq) are added, and the mixture is refluxed for 20 hours. The solvent is removed under vacuum and the residue is dissolved in CH2Cl2 and treated three times with active charcoal. After removing the solvent, the product 1-(2-chloropyrid-4-ylmethyl)-5,5-dimethyl-3-(4-trifluoromethylsulfanylphenyl)imidazolidine-2,4-dione is obtained (3.2 g; 56%).
