Vorschrift

108 mg (0.20 mmol) of the compound from Example 103A are dissolved in 3 ml of dry DMF, and 54 mg (0.39 mmol) of methyl N-methylglycinate hydrochloride and 59 mg (0.59 mmol) of triethylamine are added. The reaction mixture is stirred at RT for 8 h. The solvent is then removed on a rotary evaporator and 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.
