该中间体在本合成路线中的序号：(III)The condensation of pyridin-4-ylamine (I) with the iminodithiocarbonate (II) by means of NaH in DMF gives the isothiourea (III), which is finally condensed with 6-(4-chlorophenoxy)hexylamine (IV) by means of TEA in pyridine. Alternatively, the target guanidine can also be obtained by condensation of N-[6-(4-chlorophenoxy)hexyl]-N'-(4-pyridyl)thiourea (V) with cyanamide by means of DCC and TEA in acetonitrile.
