1-Benzyloxycarbonyl-4-(2-fluoropyrid-3-yl)piperidine → 2-Fluoro-3-(piperidin-4-YL)pyridine

Participants

Reaction Steps

A solution of 1-benzyloxycarbonyl-4-(2-fluoropyrid-3-yl)piperidine (0.36 g) in 5 mL of trifluoroacetic acid was heated to reflux for 30 minutes and evaporated. The residue thus obtained was dissolved in chloroform and evaporated. After repeating this process three times, the named product was obtained as an oil (0.64 g); MS: 181; NMR: 1.6-2.1 (m, 4), 3.0-3.4 (m, 5), 7.2-7.5 (m, 2), 7.8-7.9 (m, 4), 8.1 (m, 1), 8.2-8.8 (br, 2).
