Procedure

2-tert-Butylaniline was converted to 4-iodo-2-tert-butylaniline according to Method A5a. The aniline was converted to 4-iodo-2-tert-butylphenyl isothiocyanate according to Method A2b. 1-Amino-1-(hydroxymethyl)cyclopentane was synthesized as described in Method B1c. The 2-hydroxyethylamine was reacted with SOCl2 according to Method B7a to give 1-amino-1-(chloromethyl)cyclopentane HCl salt. The 2-chloroethylamine was reacted with 4-iodo-2-tert-butylphenyl isothiocyanate according to Method C1a to give 2-(4-iodo-2-tert-butylphenylimino)-1-thia-3-azaspiro[4.4]nonane. The thiazolidine was reacted with cyclopentyl bromide according to Method D2b to give 3-cyclopentyl-2-(4-iodo-2-tert-butylphenylimino)-1-thia-3-azaspiro[4.4]nonane. The phenyl iodide was reacted with CuCN according to Method D7a to afford 3-cyclopentyl-2-(4-cyano-2-tert-butylphenylimino)-1-thia-3-azaspiro[4.4]nonane.
