Procedure
1.35 g (4.43 mmol) of the iodinated compound obtained in Step C and 1.37 g (26.6 mmol) of potassium cyanide are dissolved in 15 ml of anhydrous hexamethylphosphoric triamide; the reaction mixture is then stirred for 2 days under argon and at ambient temperature. The solution is then hydrolysed with a solution of sodium hydrogen carbonate; the aqueous phase is then extracted with dichloromethane. The organic phase, dried over magnesium sulphate and then filtered, is concentrated under reduced pressure. The title nitrile is obtained pure in the form of a clear oil after chromatography on silica gel (eluant: PE then AcOEt/PE: 15/85).
