Versuchsvorschrift

To a 25 mL round bottom flask with magnetic stirring and condenser and under nitrogen were added the following: the solution from step 2 containing about 10.0 mmol of ethyl 4-(2-methanesulfonylethoxy)benzoate, 2 mL (20 mmol) of piperidine, and 1.5 g K2CO3. The mixture was heated to 80° C. for 24 hours and then to 125° C. for an additional 24 hours to yield product. The yield was estimated to exceed 90%. The product was identical by chromatography and 1H-NMR to that found by published methods.
