PROCESS FOR THE PREPARATION OF 2-ALKYLPIPERIDINES |
| abstract |
2-Alkyl piperidines are prepd. by hydrogenation of 2-alkyl pyridines, at 50 (5-10) atmos. over-press. and 250 (160-180) degrees C. A supported Ru catalyst is used. Alkyl gp. may contain 1-5 (1-3) C. Quantitative conversions are achieved. No solvent is used. Highly pure 2-alkyl piperidines are obtd. Catalyst can be re-used, without loss in activity. In an example, 97% pure alpha-Me piperidine was prepd. by hydrogenating alpha-picoline at 10 atmos. over-press., 170 degrees C, using 5% Ru on C as catalyst. |
