Procedimiento

72 mg (0.64 mmol) of potassium tert-butoxide are suspended in 1 ml of dry 1,2-dimethoxyethane. In succession, 270 mg (1.29 mmol) of the compound from Example 100A and 50 mg (0.13 mmol) of the compound from Example 99A are then added. The reaction mixture is stirred at 60° C. for 2 h and then cooled to RT and stirred at this temperature for a further 8 h. 5 ml of water and 1 ml of 2 N acetic acid are then added to the mixture. A precipitate is formed, which is filtered off with suction and purified by preparative HPLC (column: YMC GEL ODS-AQ S-5/15 μm; mobile phase gradient: acetonitrile/water 10:90→95:5). Removal of the solvent on a rotary evaporator gives the product as a yellow solid.
