Reaction Conditions

Reaction Steps

The compound (360 mg, 1.38 mmol) obtained in Step 3 was dissolved in acetic acid (5 mL), and sodium acetate (450 mg, 5.5 mmol) and hydroxylamine hydrochloride (140 mg, 2.1 mmol) were added thereto, and stirred at 60° C. for 2 hours. After that, acetic anhydride (0.26 mL, 2.75 mmol) was added thereto, and stirred at 100° C. for 2 hours. After cooling, the solvent was distilled away, and the resulting residue was purified by silica gel chromatography (hexane/ethyl acetate) to thus obtain the title compound.
