65 mg (0.12 mmol) of the compound from Example 101A are dissolved in 6 ml of acetic acid, and 3 ml of water are added. The mixture is stirred at RT for 30 min. The mixture is then heated to 70° C. and stirred at this temperature for a further 30 min A clear solution is formed. The mixture is then freed from the solvent on a rotary evaporator and the residue is purified by preparative HPLC (column: YMC GEL ODS-AQ S-5/15 μm; mobile phase gradient: acetonitrile/water 10:90→95:5). After removal of the solvent on a rotary evaporator, the product is obtained as a white solid.
