Versuchsvorschrift

comprising reducing 2-chloro-5-methylpyridine-3-carbaldehyde with sodium borohydride to give 2-chloro-3-hydroxymethyl-5-methylpyridine, followed by reacting the 2-chloro-3-hydroxymethyl-5-methylpyridine thus obtained with thionyl chloride to give 2-chloro-3-chloromethyl-5-methylpyridine, followed by reacting the 2-chloro-3-chloromethyl-5-methylpyridine thus obtained with 2-nitroimino-1,3-diazacyclopentane in the presence of a base and an organic solvent, to give 1-(2-chloro-5-methyl-3-pyridylmethyl)-2-nitroiminoimidazolidine.
