Procedure
45.1 mg (0.1 mmol) of the compound of Example 25 are added to 0.5 ml 2-(dimethylamino)ethanol. The reaction mixture is stirred at approx. 100° C. for 1 hour. After cooling the reaction mixture is purified by preparative HPLC (column: Agilent Zorbax Extend C18 20 mm×50 mm, 5 μm; solvent A: acetonitrile, solvent B: water+0.1% conc. ammonia; gradient: 0 min 10% A, 2 min 10% A, 6 min 90% A, 7 min 90% A, 7.1 min 10% A, 8 min 10% A; wavelength: 220 nm; injection volume: approx. 500 μl; number of injections: 1). The product containing fractions are combined and concentrated in vacuo.
