Procedure

First, 0.23 g of 5-hydroxypentyloxyacetone O-tert-butyloxime, 0.12 g of triethylamine, and 10 ml of tetrahydrofuran are placed in a reaction vessel, to which 0.14 g of methanesulfonyl chloride is slowly added with stirring under ice cooling. After completion of the addition, the reaction mixture is further stirred at room temperature for 30 minutes, poured into diluted hydrochloric acid, and extracted twice with diethyl ether. The diethyl ether layers are combined, washed with water, dried over anhydrous magnesium sulfate, and concentrated, which affords 5-(methanesulfonyloxy)pentyloxyacetone O-tert-butyloxime.
