(CAS NO.: ), with its systematic name of 1,2,4-Triazine-3,5-diamine, 6-(2,3-dichlorophenyl)-, could be produced through many synthetic methods.

Following are some of the synthesis routes:
Route one: The Grignard condensation of 2,3-dichloroiodobenzene (I) with CO₂ in the presence of Mg / ether gives 2,3-dichlorobenzoic acid (II), which is converted to the corresponding acyl chloride (III) by refluxing with SOCl₂.The reaction of (III) with cuprous cyanide and KI in refluxing xylene yields 2,3-dichlorobenzoyl cyanide (IV). Finally, this compound is cyclized with aminoguanidine (V) in DMSO.

Route two: ation of 2,3-dichloronitrobenzene (I) with H₂ over Ra-Ni in methanol gives 2,3-dichloroaniline (II), which is diazotized with NaNO₂ and HCl and treated with CuCN to yield 2,3-dichlorobenzonitrile (III). Hydrolysis of the nitrile (III) with NaOH in refluxing methanol/water affords 2,3-dichlorobenzoic acid (IV), which is treated with hot SOCl₂ to provide the corresponding acyl chloride (V). Reaction of (V) with CuCN and KI in refluxing chlorobenzene gives 2,3-dichlorobenzoyl cyanide (VI), which is condensed with aminoguanidine (VII) by means of H₂SO₄/TsOH in hot toluene to produce 2,3-dichlorobenzoyl cyanide amidinohydrazone (VIII). At last, this compound is cyclized by treatment with NaOMe in refluxing methanol.
