実験手順
3-Methyl-4-nitroaniline was converted to 3-methyl-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 3-methyl-4-nitrophenyl isothiocyanate according to Method C1a to give 2-(3-methyl-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-(3-methyl-4-nitrophenylimino)-3-thia-1-azaspiro[4.4]nonane.
