Versuchsvorschrift

3 g (14.3mmol) of the compound from Example 1 are heated for a few minutes in 10 ml of ethanol and 20 ml of conc. ammonia. A further 5 ml of conc. ammonia are then added three times each and the mixture is again briefly heated to boiling. After cooling, the precipitate is filtered off with suction and dried over P2O5 in vacuo.
