Reaction Steps

NaH (to 60%) (6 mg, 0.16 mmole) is added under argon to a solution of N-[4-(4,4-dimethyl-2,5-dioxo-3-{9-[(4,4,5,5,5-pentafluoropentyl)sulphinyl]-nonyl}imidazolidin-1-yl)-2 (trifluoromethyl)phenyl]acetamide (100 mg, 0.15 mmole) (prepared according to Example 18) in anhydrous DMF (2 ml). A release of gas accompanies the change in colour of the reaction medium. Stirring is maintained for 1 hour at 23° C. before adding methyl iodide (10 μl, 0.16 mmole). After reaction for 1 hour the same quantity of sodium hydride and methyl iodide as previously are added, then the reaction mixture is again stirred for 3 hours at 23° C. The reaction medium is poured into water (25 ml) and extracted with AcOEt (2×25 ml). The organic phases are combined and washed successively with water (25 ml) and salt water (25 ml). After drying over Na2SO4, the organic solution is filtered and concentrated under vacuum. The evaporation residue is purified on a silica column (eluent: CH2Cl2/MeOH: 95/5 to 90/10). The expected compound is obtained in the form of a colourless oil with a yield of 72% (72 mg).
