Versuchsvorschrift

The reaction was run in the same manner as ethyl 1-benzoyl-3-piperidinecarboxylate, starting with commercially available (S)-ethyl nipecotate (203 mg; 1.29 mmol; Chemi SpA; Italy) and benzoyl chloride (150 μl; 1.29 mmol). The crude product was distilled at 200° C./0.1 torr, giving (S)-ethyl 1-benzoyl-3-piperidinecarboxylate (171.7 mg) as a colorless oil. MS m/z (positive ion) 545 (dimer+Na+; 15), 523 (dimer+; 10), 284 (M+Na+; 25), 262 (MH+; 100).
