반응 단계
2-Cyano-5-nitrothiophene was reduced to 2-amino-5-cyanothiophene according to Method A1a. The aminothiophene was converted to 5-cyano-1-thiophene isothiocyanate according to Method A2b. 1-Hydroxymethylcyclopentanamine was prepared according to Method B1c. The 2-hydroxyethylamine was converted to 1-chloromethylcyclopentanamine HCl salt according to Method B7e. 1-Chloromethylcyclopentanamine HCl salt was reacted with 5-cyano-1-thiophene isothiocyanate according to Method C1e to give 2-(5-cyanothienylimino)-3-thia-1-azaspiro[4.4]nonane. The thiazolidine was reacted with isobutyl bromide according to Method D2a to give 2-(5-cyanothienylimino)-1-isobutyl-3-thia-1-azaspiro[4.4]nonane.
