Reaction Steps

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 animmonium acetate. After returning to room temperature and evaporation to dryness, the reaction mixture is diluted in dichloromethane and washed with water.
