실험 절차
Methyl 4-amino-3-methylbenzoate was converted to 4-methoxycarbonyl-2-methylphenyl isothiocyanate according to Method A2b. 1-Hydroxymethylcyclopentanamine was prepared according to Method B1c. The 2-hydroxyethylamine was sequentially reacted with SOCl2 and 4-methoxycarbonyl-2-methylphenyl isothiocyanate according to Method C2a to give 2-(4-methoxycarbonyl-2-methylphenylimino)-3-thia-1-azaspiro[4.4]nonane. The thiazolidine was reacted with cyclopentyl bromide according to Method D2h to give 2-(4-methoxycarbonyl-2-methylphenylimino)-1-cyclopentyl-3-thia-1-azaspiro[4.4]nonane.
