Versuchsvorschrift

Ethyl 1-benzoyl-3-piperidinecarboxylate (431.4 mg; 1.65 mmol) was dissolved in absolute ethanol (10 ml), and after addition of 1 N sodium hydroxide (20 ml), the mixture was allowed to stir at ambient temperature for approximately 1 hour. It was then poured into 1 N hydrochloric acid and extracted with dichloromethane. The dichloromethane was dried with anhydrous magnesium sulfate and then evaporated at ambient temperature under reduced pressure, giving 1-benzoyl-3-piperidine carboxylic acid (327.3 mg) as a white solid without further purification. MS m/z (negative ion) 232 (M-H; 100), 188 (M-CO2H; 90).
