Versuchsvorschrift

5.00 g (12.1 mmol) of the compound from Example 45A, 3.57 g (36.4 mmol) of thiomorpholine and 5.03 g (36.4 mmol) of potassium carbonate were added to 76 ml of DMF and heated in 5 portions in a single-mode microwave (Emrys Optimizer) at 150° C. for 1.5 h. For workup, the reaction solutions were combined and filtered, and the residue was purified by means of preparative HPLC. Yield: 3.07 g (67% of theory)
