Reaction Conditions

Reaction Steps

145 mg (0.46 mmol) of the compound from Example 64A were dissolved in 3 ml of acetonitrile, and 141 mg (0.46 mmol) of the compound from Example 5A and 224 mg (0.69 mmol) of cesium carbonate were added. The mixture was stirred at 60° C. for 16 h. After cooling to RT, the solid was filtered off and rinsed with a little acetonitrile. Under reduced pressure, the filtrate was reduced to a volume of about 2 ml, 0.1 ml of 1 N hydrochloric acid was added and the product was directly purified chromatographically [Method 19]. This gave 49 mg (20% of theory) of the target compound.
