合成路线1

该中间体在本合成路线中的序号：(VI)

The reaction of 5(R)-(azidomethyl)-3-phenyloxazolidin-2-one (I) with Ac2O and MsOH gives the 4-acetylphenyl derivative (II), which is cyclized with glyoxylic acid (III) and hydrazine (IV) in hot acetic acid to yield the pyridazinone derivative (V). The reduction of the azido group of (V) by means of PPh3 in THF/water affords the aminomethyl compound (VI), which is finally condensed with ethyl dithioacetate (VII) by means of TEA in DMF to provide the target thioacetamide.

Finally, this compound is treated with Lawesson's reagent in hot dioxane to furnish the target pyridazinethione.
