Versuchsvorschrift

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-methyl-4-nitrophenyl isothiocyanate according to Method C1e to give 2-(2-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-(2-methyl-4-nitrophenylimino)-3-thia-1-azaspiro[4.4]nonane.
