Reaction Steps

A solution of 37.26 g. (0.214 mole) of 4-carbomethoxy-3-keto-2-methyltetrahydrothiophene in 100 ml. anhydrous pyridine was treated with 18.0 g. (0.261 mole) hydroxylamine hydrochloride. The mixture was stirred 24 hours at 25°. The reaction was concentrated and partitioned between 1 N hydrochloric acid/methylene chloride. The aqueous phase was extracted two times with methylene chloride. The combined organic extracts were dried and evaporated to yield 40.1 g (99%) of pure 4-carbomethoxy-3-keto-2-methyltetrahydrothiophene oxime as a colorless oil.
