合成路线1

The reaction of benzohydroxamic acid (I) with benzyl bromide (II) by means of NaOH on ethanol gives the corresponding benzyl ester (III), which is treated with HCl yielding O-benzylhydroxylamine (IV). The reaction of (IV) with dicyaniamide (V) in ethanol affords the biguanide (VI), which is cyclized with cyclopentanone (VII) and HCl giving 1-benzyloxy-2,2-dimethyl-1,2-dihydro-1,3,5-triazine-4,6-diamine (VIII). The debenzylation of (VIII) with H2 over PtO2 in ethanol yields 1-hydroxy-2,2-dimethyl-1,2-dihydro-1,3,5-triazine-4,6-diamine (IX), which is finally condensed with 1,6-dibromohexane (X) by means of NaOH in methanol.

The reaction of benzohydroxamic acid (I) with 1,6-dibromohexane (X) by means of NaOH in methanol gives the bis benzohydroxamic ester (XI), which is treated with HCl to afford the subituted bis hydroxylamine (XII). The reaction of (XII) with dicyandiamide (V) in ethanol yields the bis biguanide (XIII), which is finally cyclized with cyclopentanone (VII) and HCl as before.
