Trifluoroacetic acid → N,N-Dimethyl-3-piperidinecarboxamide

Participants

Reaction Steps

This reaction was run in the same manner as ethyl 3-piperidinylacetate, starting with commercially available N,N-dimethylnicotinamide (10 g; 66.7 mmol) and platinum oxide (1.02 g; 4.49 mmol). Trifluoroacetic acid (5.1 ml; 66.2 mmol) was used in place of L(+) tartaric acid. Crude product was purified by distillation at approximately 150° C./10 torr, giving N,N-dimethyl-3-piperidinecarboxamide (4.0 g) as a colorless oil. MS m/z (positive ion) 157 (MH+: 100).
