Procedure
3.3 mL of triethylamine was added to a solution of 3.6 g of 5-(methoxyimino)-4-phenoxypentan-2-ol in 36 mL of tetrahydrofuran, and thereafter, 1.2 mL of methanesulfonyl chloride was added to the mixture at a temperature of 0° C. to 10° C. The obtained mixture was stirred at 15° C. or lower for 1 hour. Thereafter, 200 mL of ethyl acetate and 200 mL of water were added to the reaction mixture, and the water layer was then removed. The organic layer was dried over anhydrous magnesium sulfate, and the solvent was then distilled away under reduced pressure. The obtained residue was purified by silica gel column chromatography (hexane/ethyl acetate=4/1), so as to obtain 4.4 g of 5-(methoxyimino)-4-phenoxypentan-2-yl methanesulfonate in the form of a light yellow oily product.
