Versuchsvorschrift
600 mg (2.27 mmol) of the compound obtained in Step E dissolved in 25 ml of nitromethane are heated at 120° C., for 3 hours in the presence of 440 mg (5.67 mmol) of ammonium acetate. After returning to room temperature and evaporation to dryness, the reaction mixture is diluted in dichloromethane and washed with water. After drying over magnesium sulphate, evaporation of the organic phase yields the title compound in the form of a yellow solid.
