4. 4
   Otheron a rotary evaporator
5. 5
   Otherthe product is obtained as a white solid

Procedure

400 mg (0.70 mmol) of the compound from Example 46A are initially charged in 17 ml of acetic acid, and 8.6 ml of water are then added carefully. The mixture is stirred at RT for 12 h. After concentration of the reaction mixture on a rotary evaporator, the residue is purified directly 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.
