11.1 g (50 mmol) of methyl 2-isothiocyanato- 2-phenylpropionate are dissolved in 150 ml of anhydrous tetrahydrofuran. A solution containing 5.4 g (50 mmol) of phenylhydrazine and 50 ml of anhydrous tetrahydrofuran is added progressively over 10 min: the temperature of the mixture rises to 35"C. On completion of addition, the mixture is left to react for 0.5 h at 30"C and the mixture is then cooled to A solution containing 5.6 g (50 mmol) of potassium tert-butoxide and 50 ml of anhydrous tetrahydrofuran is added at this temperature: the mixture turns violet in colour and then a precipitate forms. The mixture is left to react 15 for 0.5 h at 0°C and then 8.5 g (60 mmol) of methyl iodide are added. The mixture is left to react for 1 h at room temperature. The mixture is diluted with 200 ml of ethyl acetate. The mixture is washed 2 times with 150 ml of water on each occasion. The solution is dried 20 over magnesium sulphate and then treated with active charcoal. The solution is concentrated: a purplishbrown honey-like prodw t is obtained which is crystallised from 50 ml of ether. The precipitate is washed and then dried under vacuum. A second crop of product is recovered after concentrating the mother liquors and taking up the residual honey-like product in 50 ml of diisopropyl ether. 12 g (yield 77 of 4-methyl-2-methylthio-4-phenyl-l-phenylamino-2- I 38 (compound 9) are thus obtained in the form of a beige powder melting at 149"C.

0.6 g (2.7 mmol) of 2-methylthio-4-methyl-4phenyl-2-imidazolin-5-one in solution in 50 ml of anhydrous tetrahydrofuran (THF) is charged to a 100 ml, three-necked, round-bottomed flask under an inert atmosphere. The solution is stirred with a magnetic stirrer and is cooled to O'C (ice bath acetone).
0.30 g (1 molar equivalent) of potassium tert-butoxide is added and the mixture is stirred for 10 min at 0OC.
A solution containing 0.40 g of phenylsulphenyl chloride and 10 ml of anhydrous THF is then run in. The mixture is then left to return to room temperature for 15 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 sulphate.
The organic phase is concentrated under vacuum. A yellow honey-like product is obtained which crystallises from isopropyl ether after purification on silica with a yield of 68% (melting point: 112"C).
