実験手順
7.45 g (20 mmol) of the compound from Example 1, 2.08 g (30 mmol) of hydoxylammonium chloride and 4.14 g (30 mmol) of potassium carbonate are refluxed in 20 ml of ethanol for 15 h. After cooling to room temperature, the mixture is evaporated and the residue is stirred in 50 ml of water for 3 h (after this time no oily residues, but only crystalline residues, were still undissolved). The precipitate was filtered off, washed with water and recrystallised from methanol by addition of water. Yield: 5.71 g (73.7% of theory) M.p.: 170° C.
