Second-Generation Process Research Towards Eletriptan: A Fischer Indole Approach
摘要:
The development of a second-generation process for the synthesis of eletriptan via a Fischer indole cyclisation is described. The finalised process offers several potential advantages over the current route of manufacture including cost, throughput, and safety.

The present invention relates to a new process for the preparation of eletriptan (I), or its enantiomer comprising a modified Fischer indole synthesis, namely the reaction of a compound of formula (II), wherein R1 is a suitable hydrazine protecting group, with a compound of formula (III) wherein R2 is an aldehyde group (-CHO) or the functional equivalent thereof.
