Procedure
4-Iodo-2,3-dimethylaniline was converted to 4-iodo-2,3-dimethylphenyl isothiocyanate according to Method A2b. 1-Hydroxymethylcyclopentanamine was prepared according to Method B1c. The 2-hydroxyethylamine was sequentially reacted with SOCl2 and 4-iodo-2,3-dimethylphenyl isothiocyanate according to Method C2a to give 2-(4-iodo-2,3-dimethylphenylimino)-3-thia-1-azaspiro[4.4]nonane. The thiazolidine was reacted with cyclopentyl bromide according to Method D2b to give 2-(4-iodo-2,3-dimethylphenylimino)-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-2,3-dimethylphenylimino)-1-cyclopentyl-3-thia-1-azaspiro[4.4]nonane.
