Reaction Steps

2-n-Propylaniline was converted to 2-n-propylacetanilide according to Method A2a, Step 1. The acetanilide was converted to 2-n-propyl-4-nitroacetanilide according to Method A2a, Step 2. The acetanilide was deprotected according to Method A2a, Step 3 to give 2-n-propyl-4-nitroaniline. The aniline was converted to 2-n-propyl-4-nitrophenyl 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 2-n-propyl-4-nitrophenyl isothiocyanate according to Method C1a to give 2-(2-n-propyl-4-nitrophenylimino)-3-thia-1-azaspiro[4.4]nonane. The thiazolidine was reacted with isobutyl bromide according to Method D2a to afford 1-isobutyl-2-(2-n-propyl-14-nitrophenylimino)-3-thia-1-azaspiro[4.4]nonane.
