Procedure

2.36 g (12.75 mmol) of potassium phthalimide and also 0.166 g (1 mmol) of potassium iodide are added to a solution of 2.54 g (8.5 mmol) of the brominated compound obtained in Step E in 20 ml of anhydrous N,N-dimethylformamide; the medium is then stirred under argon for 10 hours. The solvent is evaporated in vacuo; the residue obtained is then taken up in water and extracted with dichloromethane. The organic phase is dried over magnesium sulphate and then concentrated under reduced pressure. Chromatography on a silica column (eluant:ethyl acetate/petroleum ether 10/90) yields the title phthalimide in the form of a white solid.
