Procedure
Amidine (e) is readily produced from nitrites. More specifically, hydroxylamine hydrochloride dissolved in a suitable solvent, such as water, is reacted with cyanopiperidine (g) in the presence of a base such as sodium carbonate in a suitable solvent, such as in methanol and exposed to heat to provide the hydroxycarbamimidoyl-piperidine (h). The hydroxycarbamimidoylpiperidine (h) in a suitable solvent, such as acetic acid, is then hydrogenated via palladium catalyst in the presence of acetic acid anhydride under pressure to provide amidine (e).
