tert-Butyl 3-(3-benzyloxypropyl)-6-[3-(2,2-dimethylpropyl)cyclobutyl]-4-methoxyimino-5-hexynoate (3.37 g) and methylene chloride (70 mL) were mixed. To the mixture was added iodine monochloride (1 M in methylene chloride) (7.66 mL) at ice temperature. The mixture was stirred at ice temperature for 1 hr, and then to the mixture was added aqueous solution of sodium sulfite. The mixture was extracted with chloroform. The organic layer was washed with water and brine, then dried over magnesium sulfate. The magnesium sulfate was filtered off and the filtrate was concentrated in vacuo to give the title compound (4.21 g) as a crude product.
