Vorschrift

260 mg (0.608 mmol) of 5-chloro-N-(3-{[3-fluoro-4-(3-oxo-4-morpholinyl)phenyl]-amino}-2-hydroxypropyl)-2-thiophenecarboxamide (from Example 61), 197 mg (1.22 mmol) of carbonylimidazole and 7 mg of dimethylaminopyridine in 20 ml of dioxane are boiled under reflux for 5 hours. 20 ml of acetonitrile are then added, and the mixture is stirred in a closed vessel in a microwave oven at 180° C. for 30 minutes. The solution is concentrated using a rotary evaporator and chromatographed on an RP-HPLC column. This gives 53 mg (19% of theory) of the target compound.
