New intermediates for the preparation of remifentanil hydrochloride |
| abstract |
A new intermediate for synthesizing 1-substituted-4-[phenyl(propanoyl)amino]piperidine-4-carbonitrile derivatives is laid open. Specifically set out is a method for use of this intermediate in the preparation of remifentanil. The enclosed shorter process offers a greater yield of products with higher purity as compared to methods reported in the prior art. |
