The saturated cyano compound obtained in Step B is solubilized in the reactor of a Parr apparatus with acetic anhydride. Sodium acetate (1.5 eq.) and also Raney nickel (6 mg per 50 mg of product) are then introduced into the reaction medium. The whole is heated at 50° C. under hydrogen pressure of 40 psi for 12 hours. Once the solvent has been removed after returning to normal temperature and pressure conditions, extraction is carried out with ethyl acetate. Purification of the concentrated organic phase by flash chromatography (CHCl3/AcOEt 7/3) results in the desired amide. Colourless gum.
