Procedure

Ten (10) mg (19.4 μmol) fredericamycin aldehyde (4) are dissolved in 2 mL DMF. After addition of 6.4 mg (43.2 μmol) O-benzylhydroxylammonium chloride and 3.2 μl pyridine, the reaction mixture is stirred for 2 h at room temperature. Then, it is added to 50 ml water, and the supernatant is sucked off from the red precipitate (HPLC clean).
