合成路线1
The reaction of 2,4,5-trichlorophenol (I) with 1,3-dibromopropane (II) by means of refluxing 25% aqueous NaOH gives 3-(2,4,5-trichlorophenoxy)propyl bromide (III), which is condensed with benzhydroxamic acid (IV) by means of NaOH in refluxing methanol yielding 3-(2,4,5-trichlorophenoxy)propyl benzhydroxamate (V). The hydrolysis of (V) with HCl in refluxing methanol affords 3-(2,4,5-trichlorophenoxy)propyloxyamine (VI), which is then condensed with dicyandiamide (VII) in refluxing ethanol to give 3'-(2,4,5-trichlorophenoxy)propyloxydiguanide (VIII). Finally, this compound is cyclized with acetone (IX) by means of HCl.
