合成路线1
The reaction of m-xylenediamine (I) with triethylamine and di-tert-butyldicarbonate (II) gives the corresponding tert-butyl N-[3-(aminomethyl)benzyl] carbamate hydrochloride (III), which is converted into the tert-butyl N-[3-((acetimidoyl)aminomethyl]benzyl) carbamate hydrochloride (VII) by reaction with S-benzylthioacetimidate hydrochloride (VI). This intermediate (VI) could be obtained by reaction of thioacetamide (IV) with benzyl chloride (V). Finally, compound (VII) is deprotected with HCl to afford the corresponding N-[3-(aminomethyl)benzyl] acetamidine hydrochloride.
