実験手順

41 mg (0.17 mmol) of the compound from Example 12A were dissolved in 2 ml of DMF, and 48 mg (0.17 mmol) of the compound from Example 40A and 85 mg (0.26 mmol) of cesium carbonate were added. The mixture was stirred at 80° C. for 16 h. After cooling to RT, the reaction mixture was diluted with 1 ml of methanol and directly purified chromatographically [Method 19]. This gave 4 mg (5% of theory) of the target compound.
