Procedure

To a mixture of the compound (190 mg) obtained in Example 289, triethylamine (0.14 ml), O-methylhydroxylamine hydrochloride (84 mg) and acetonitrile (5 ml), a solution of silver nitrate (90 mg) in acetonitrile (2 ml) was added and stirred at 0° C. for 15 min. The reaction mixture was filtered through Celite and the filtrate was concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography (eluent, chloroform:ethyl acetate=3:1) to give the 75 mg of titled compound (yield, 38%).
