Reaction Steps

0.2 g (0.74 mmol) of the amine obtained in Step C is dissolved in 3 ml of anhydrous pyridine; the solution is then cooled to 0° C. After addition of 0.085 ml (0.89 mmol) of acetic anhydride, the reaction medium is stirred for 1 hour at 0° C. The solution is then diluted with dichloromethane and then acidified with a hydrochloric acid solution (1N). The aqueous phase is extracted with dichloromethane; the organic phase is then dried over magnesium sulphate. After evaporation of the solvent in vacuo, the residue obtained is purified on a silica column (eluant: AcOEt/PE: 60/40) to yield the title amide in the form of a white solid.
