Reaction Steps

1.25 g (6.75 mmol) of potassium phthalimide are added to a solution of 1.4 g (4.5 mmol) of the brominated compound obtained in Step D in 15 ml of DMF; the medium is then stirred overnight at ambient temperature and under argon. After evaporation of the solvent in vacuo, the residue obtained is taken up in water; the aqueous phase is then extracted with dichloromethane. The organic phase, dried over magnesium sulphate and then filtered, is concentrated in vacuo. Chromatography on a silica column (eluant:ethyl acetate/petroleum ether 10/90) allows access to the title phthalimide in the form of a white solid.
