Procedure

4-Iodo-2-n-propylaniline was converted to 4-iodo-2-n-propylphenyl isothiocyanate according to Method A2b. 1-Hydroxymethylcyclopentanamine was prepared according to Method B1c. The 2-hydroxyethylamine was sequentially reacted with SOCl2 and 4-iodo-2-n-propylphenyl isothiocyanate according to Method C2a to give 2-(4-iodo-2-n-propylphenylimino)-3-thia-1-azaspiro[4.4]nonane. The thiazolidine was reacted with cyclopentyl bromide according to Method D2b to give 2-(4-iodo-2-n-propylphenylimino)-1-cyclopentyl-3-thia-1-azaspiro[4.4]nonane. The phenyl iodide was reacted with CuCN according to Method D7a to afford 2-(4-cyano-2-n-propylphenylimino)-1-cyclopentyl-3-thia-1-azaspiro[4.4]nonane.
