Reaction Steps

2-Piperidenemethanol was made from methyl pipecolinate as described in Method B1b. The 2-hydroxyethylamine was converted to 2-chloromethylpiperidinium chloride according to Method B7a. 2-Methyl4-nitrophenyl isothiocyanate was reacted with 2-chloromethylpiperidinium chloride according according to Method C1a to give 9-(2-methyl-4-nitrophenylimino)-1-aza-8-thiabicyclo[4.3.0]nonane.
