Procedure
4-Cyano-2-methylaniline was synthesized as described in Method A1a. The aniline was converted to 4-cyano-2-methylphenyl isothiocyanate according to Method A2a, Step 3. 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-cyano-2-methylphenyl isothiocyanate according to Method C1a to give 2-(4-cyano-2-methylphenylimino)-1-thia-3-azaspiro[4.4]nonane. The thiazolidine was reacted with isobutyl bromide according to Method D2b to give 3-isobutyl-2-(4-iodo-2-methylphenylimino)-1-thia-3-azaspiro[4.4]nonane.
