Procedure

10.5 mL of boron trifluoride/dimethyl sulphide complex are added dropwise, at ambient temperature, to 3.7 g of a solution of 3-(3,4-dichlorophenyl)-5-(3-methoxyphenyl)-1-methylimidazolidine-2,4-dione in 60 mL of dichloromethane in a flask equipped with a magnetic stirrer and a nitrogen intake. After 2 hours at ambient temperature, the mixture is poured over a saturated aqueous sodium bicarbonate solution and subjected to extraction with ethyl acetate. The mixture is dried over magnesium sulphate and concentrated. The residue is crystallised in isopropyl ether (white solid; m=3 g; Yd=84%).
