Procedure

20 mL of methanol and 1.8 g of O-methylhydroxylamine hydrochloride were added to 3.6 g of 5-methyl-3-phenoxyoxolan-2-ol that was a colorless oily product, and thereafter, 2.79 mL of triethylamine was added dropwise to the mixture. The thus obtained mixture was stirred at room temperature for 5.5 hours. Thereafter, methanol was distilled away under reduced pressure, 100 mL of ethyl acetate and 100 mL of water were then added to the residue, 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, so as to obtain 3.65 g of 5-(methoxyimino)-4-phenoxypentan-2-ol in the form of a colorless oily product.
