Versuchsvorschrift
0.17 mol of the compound obtained in Stage A of Example 3, dissolved in 200 ml of phosphorus oxychloride, is brought to 85° C. for one hour 30 minutes. The phosphorus oxychloride is then removed by evaporation under vacuum. 100 ml of water are added and the pH is adjusted to 7 using sodium bicarbonate to crystallize the expected compound. The latter is filtered off.
