合成路线1
该中间体在本合成路线中的序号：(III)The cyclization of dimethylaminothioacetamide (I) with ethyl bromopyruvate (II) in refluxing ethanol gives ethyl 2-(dimethylaminomethyl)-4-thiazolecarboxylate (III), which is reduced with lithium triethyl borohydride in THF yielding 2-(dimethylaminomethyl)-4-thiazolemethanol (IV). The condensation of (IV) with 2-aminoethanethiol (V) by means of 48% HBr affords 2-(dimethylaminomethyl)-4-(2-aminoethylthiomethyl)thiazole (VI), which is finally condensed with 1-(methylthio)-2-nitro-N-methylethyleneamine (VII) in water.
