Analgesic Patent | Bookmark | |||||
While farting around at http://gb.espacenet.com/, I found a patent that I think is interesting: GB801577 Lower alkyl 4-phenyl-1-(hydrocarbyl) piperidine-4-carboxylates and the preparation thereof http://l2.espacenet.com/espacenet/viewer Love my country, fear my government. |

Interesting, hmm ..., it most definitely is. This ethyl 4-phenyl-1-(3-phenylpropyl)-piperidine-4 The only problem with this patent would be the synthesis of the ethyl 4-phenylpiperidine-4-carboxylate hydrochloride precursor. This is not like a easy thing to do ![]() For mor information about pethidine & analogs see: http://www.undcp.org/bulletin/bulletin_1 |
