Procedure

0.6 g (2.7 mmol) of 2-methylthio-4-methyl-4-phenyl-2-imidazolin-5-one in solution in 50 ml of anhydrous tetrahydrofuran (THF) is charged to a 10 0 ml, three-necked, round-bottomed flask under an inert atmosphere. The solution is stirred with a magnetic stirrer and is cooled to 0° C. (ice bath+acetone). 0.30 g (1 molar equivalent) of potassium tert-butoxide is added and the mixture is stirred for 10 minutes at 0° C. A solution containing 0.40 g of phenylsulfonyl chloride (phenylthio chloride) and 10 ml of anhydrous THF is then run in. The mixture is then left to return to more temperature for one hour. The reaction mixture is run into 100 ml of water. Extraction is carried out with 100 ml of ethyl acetate. The organic phase is washed 4 times with water and dried over sodium sulfate.
