Versuchsvorschrift
By the method described in Example 5, the title compound of Example 4 (1.2 g, 3.6 mmol) in 40 mL of THF was converted to its mixed anhydride with NMM (0.42 g, 3.6 mmol) and IBCF (0.49 g, 3.6 mmol) and coupled to N,O-dimethylhydroxylamine . HCl (0.35 g, 3.6 mmol) using an additional 0.36 mmol (3.6 mmol) of NMM to liberate the free base of N,O-dimethylhydroxylamine . HCl. This procedure gave 726 mg of the title compound after HPLC purification on silica gel.
