110 mg (0.47 mmol) of the compound from Example 12A were dissolved in 10 ml of DMF, and 150 mg (0.47 mmol) of the compound from Example 41A and 229 mg (0.70 mmol) of cesium carbonate were added. The mixture was stirred at 80° C. for 16 h. After cooling to RT, the reaction mixture was added to about 25 ml of ice-water and stirred for 10 min. This resulted in the formation of a precipitate which was filtered off with suction and washed with water. The solid was dried under high vacuum. This gave 120 mg (44% of theory) of the target compound of a purity of 90%.
