1-Amino-1-(hydroxymethyl)cyclohexane (Method B1a) was dissolved in p-dioxane (80 mL) then treated with SOCl2 followed by 2-methyl-4-nitrophenyl isothiocyanate in a manner analogous to Method C2a to give 2-(2-methyl-4-nitrophenylimino)-3-thia-1-azaspiro[4.5]decane (20%), which was reacted with isobutyl bromide in a manner analogous to Method D2a to yield 1-isobutyl-2-(2-methyl-4-nitrophenylimino)-3-thia-1-azaspiro[4.5]decane (0.026 g, 2%): TLC (20% EtOAc/hex) Rf0.69.
