Versuchsvorschrift

A mixture of 1.0 g (6.9 mmol) of the compound from Example 7A and 1.1 g (7.6 mmol) 1-(2-methoxyethyl)piperazine in 10 ml water is stirred at 100° C. for 2 h. A further 0.9 g (6.2 mmol) 1-(2-methoxyethyl)piperazine is added and the reaction mixture is stirred further at 100° C. for 16 h. After concentration in vacuo, the residue is stirred in acetonitrile. The solid which has precipitated out is filtered off, washed first with ethanol and then with diethyl ether and dried in vacuo.
