实验步骤: 3.0 g (16.4 mmol) of the compound from Example I are boiled under reflux for 17 hours in 250 ml of a saturated methanolic ammonia solution. The reaction mixture is evaporated in vacuo, the residue is taken up in methanol and the mixture is evaporated again; this process is repeated a few times. The crude product is taken up in dichloromethane and extracted several times with water. The aqueous phase is evaporated to a very great extent, an oil being obtained which crystallizes on standing.
