Reaction Steps

1.2 mL of triethylamine was added to a solution of 1.7 g of 5-(methoxyimino)-4-(pyridin-2-ylsulfanyl)pentan-2-ol in 7.0 mL of tetrahydrofuran, and thereafter, 602 μL of methanesulfonyl chloride was added to the mixture at a temperature of 0° C. to 10° C. The thus obtained mixture was stirred at a temperature of 15° C. or lower for 1.5 hours. Thereafter, 50 mL of ethyl acetate and 50 mL of water were added to the reaction mixture, and the water layer was then removed. The organic layer was washed with a saturated sodium chloride aqueous solution, and was then dried over anhydrous magnesium sulfate. After that, the solvent was distilled away under reduced pressure, so as to obtain 2.12 g of 5-(methoxyimino)-4-(pyridin-2-ylsulfanyl)pentan-2-yl methanesulfonate in the form of a brown oily product.
