실험 절차

1-Amninocyclohexane-1-carboxylic acid was protected as the benzyloxycarbonylamine according to Method B1a, Step 1. 1-(Benzyloxycarbonylamino)cyclohexane-1-carboxylic acid was reduced to 1-(benzyloxycarbonylamino)-1-(hydroxymethyl)cyclohexane according to Method B1a, Step 2. The carbamate was deprotected according to Method B1a, Step 3 to give 1-amino-1-(hydroxymethyl)cyclohexane. The 2-hydroxyethylamine was sequentially treated with SOCl2 and 2-methyl-4-nitrophenyl isothiocyanate according to Method C2a to give 2-(2-methyl-4-nitrophenylimino)-3-thia-1-azaspiro[4.5]decane. The thiazolidine was alkylated with isobutyl bromide according to Method D2b to afford 2-(2-methyl-4-nitrophenylimino)-1-isobutyl-3-thia-1-azaspiro[4.5]decane.
