Versuchsvorschrift

To a solution of 2-(2-methyl-4-nitrophenylimino)-3-thia-1-azaspiro[4.4]nonane (Method C2a; 0.10g, 0.3432 mmol) and bromomethylcyclohexane (1.00 mL) in DMF (1.00 mL) was added NaOH (approx. 0.13 g). The resulting mixture was stirred at 45° C. for 2 d during which it turned from deep red to bright orange. The reaction mixture was then cooled to room temp., filtered and concentrated under reduced pressure. The residual oil was purified by chromatography (SiO2; 5% EtOAc/hex) to afford 1-(cyclohexylmethyl)-2-(2-methyl-4-nitrophenylimino)-3-thia-1-azaspiro[4.4]nonane (0.042 g, 32%) mp 85-7° C.
