Reaction Steps

2,3-Dimethylaniline was converted to 2,3-dimethyl-4-iodoaniline according to Method A5a. The aniline was converted to 2,3-dimethyl-4-iodophenyl 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 B7e to give 1-amino-1-(chloromethyl)cyclopentane HCl salt. The 2-chloroethylamine was reacted with 2,3-dimethyl-4-iodophenyl isothiocyanate according to Method C1e to give 2-(2,3-dimethyl-4-iodophenylimino)-1-thia-3-azaspiro[4.4]nonane. The thiazolidine was reacted with isobutyl bromide according to Method D2h to give 3-isobutyl-2-(4-iodo-2-n-propylphenylimino)-1-thia-3-azaspiro[4.4]nonane. The phenyl iodide was reacted with CuCN according to Method D7a to afford 3-isobutyl-2-(2,3-dimethyl-4-cyanophenylimino)-1-thia-3-azaspiro[4.4]nonane.
