Reaction Conditions

Reaction Steps

1 g (3.47 mmol) of the iodinated compound obtained in Step D and 0.964 g (5.2 mmol) of potassium phthalimide are dissolved in 20 ml of anhydrous N,N-dimethylformamide; the reaction mixture is then heated at 60° C. for 22 hours under argon. After cooling of the mixture, the solvent is evaporated in vacuo; the residue is then taken up in ethyl acetate. After washing with water and extraction of the aqueous phase with ethyl acetate, the organic phases are dried over magnesium sulphate. The solvent is then evaporated in vacuo; the title phthalimide is then obtained pure in the form of a white solid after passage over a silica column (eluant: AcOEt/PE: 30/70).
