Reaction Steps
3-Methyl-4-nitroaniline was converted to 3-methyl-4-nitrophenyl isothiocyanate according to Method A2a, Step 3. 1-Hydroxymethylcyclopentanamine was prepared according to Method B1c. The 2-hydroxyethylamine was converted to 1-chloromethylcyclopentanamine HCl salt according to Method B7e. 1-Chloromethylcyclopentanamine HCl salt was reacted with 3-methyl-4-nitrophenyl isothiocyanate according to Method C1e to give 2-(3-methyl-4-nitrophenylimino)-3-thia-1-azaspiro[4.4]nonane. The thiazolidine was reacted with cyclopentyl bromide according to Method D2b to give 2-(3-methyl-4-nitrophenylimino)-1-cyclopentyl-3-thia-1-azaspiro [4.4]nonane.
