Procedure

A sodium hypochlorite solution (5%, 18.5 mL) was added to a solution of 3-methoxyhept-6-enal oxime obtained in Preparation Example 57-(3) (1.95 g) in dichloromethane, and the mixture was stirred at room temperature for one hour and 10 minutes. The excess of sodium hypochlorite was decomposed with sodium thiosulfate, followed by extraction with chloroform three times. The resulting organic layers were dried over anhydrous magnesium sulfate. The drying agent was removed by filtration and then the filtrate was concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography to obtain the title compound (796 mg).
