Feclemine (phenetamine) is a spasmolytic drug.^[1]

Synthesis

The chemical synthesis is discussed:^[2]

Sodamide is used to alkylate cyclohexylphenylacetonitrile [3893-23-0] (1) (also used for drofenine) with 2-chloro-N,N,N',N'-tetraethylpropane-1,3-diamine [3492-54-4] (HCl: [94465-65-3]) to give (2). Some rearrangement is possible to give a mixture of regioisomers. Sodamide catalyzed cleavage of the nitrile group in a separate step then completes the synthesis of feclemine (3).
