experimental part, p. 1421 - 1424 (2010/06/14)
An improved process for the synthesis of sufentanil with an overall yield of 26% is described. The reactive and high yielding N-debenzylation of the piperidine intermediate 7 using a mixture of Pd/C and Pd(OH)2 was applied to other drug intermediates affording free amines in short reaction times. The deuterium-labeled sufentanil and the metabolite desmethylsufentanil were synthesized applying the optimized process.

Method for preparing 4-alkoxyalkyl-4-phenylaminopiperdines and derivatives thereof
-
, (2008/06/13)
The present invention is directed to a method for preparing a 4-alkoxyalkyl-4-phenylaminopiperidine compound which comprises the steps of (a) reacting an N-substituted-4-piperidone compound with an aniline compound to form a Schiff base compound, (b) reacting the Schiff base compound with an anionic reagent having an anion stabilizing group to form an amine compound, and (c) reducing the amine compound in step (b) with a reducing agent to displace the anion stabilizing group. The anionic reagent in step (b) above has the general formula: wherein X is an anion stabilizing group, Y is hydrogen or lower-alkyl, Z is lower-alkoxy or phenylmethoxy, M is an alkali or alkaline earth metal, and C is a carbon atom.
