Participants

Reaction Steps

The compound (20 mg, 0.04 mmol) of Example 54 was dissolved in acetic acid (5 mL), and sodium acetate (45 mg, 0.56 mmol) and hydroxylamine hydrochloride (14 mg, 0.21 mmol) were added thereto, and at 60° C. for 2 hours and stirred. After that, acetic anhydride (0.026 mL, 0.28 mmol) were added to, at 100° C. for 2 hours and stirred. After cooling, the solvent was distilled away, and the resulting residue was purified by reversed-phase HPLC in the same manner as in Step 2 of Example 1 to thus obtain the title compound.
