Versuchsvorschrift

In an argon atmosphere, a mixture of methyl benzoate (3.0 mmol), piperidin-4-ol (3.6 mmol), Zn4(OCOCF3)6O (1.25 mol % in terms of mole number) and diisopropyl ether/1,4-dioxane (3/1) (5.0 ml) was heated to reflux for 46 hours, and as a result, piperidin-4-yl benzoate was obtained at a yield of 65%. The yield of N-benzoylpiperidin-4-yl benzoate was 30%.
