Reaction Steps

1-(Hydroxymethyl)cyclopentanamine was prepared according to Method B1c. The 2-hydroxyethylamine was sequentially reacted with SOCl2 and 2-methyl-4-nitrophenyl isothiocyanate according to Method C2a to give 2-(2-methyl-4-nitrophenylimino)-3-thia-1-azaspiro[4.4]nonane. The thiazolidine was reacted with 1-bromo-2-ethylbutane according to Method D2a to afford 2-(2-methyl-4-nitrophenylimino)-1-(2-ethyl-1-butyl)-3-thia-1-azaspiro[4.4]nonane.
