合成路线1
The acylation of 4-aminothiophenol (I) with ethyl chloroformate (II) is performed in a nitrogen atmosphere in the presence of NaHCO3 in CH2Cl2 / water medium giving ethyl (4-mercaptophenyl)carbamate (III). This compound is condensed with cis-[2-(2,4-dichlorophenyl)-2-(1H-imidazol-1-ylmethyl)-1,3-dixolan-4-yl]methyl methanesulfonate (IV) in the presence of K2CO3 in refluxing acetone under nitrogen, affording the title compound, which is converted to the monohydrochloride with i-PrOH / HCl in 4-methyl-2-pentanone.

Coupling of (IV) in a nitrogen atmosphere with 4-acetamidothiophenol (V) in refluxing acetone in the presence of K2CO3 affords cis-N-[4-[2-(2,4-dichlorophenyl)-2-(1H-imidazol-1-ylmethyl)-1,3-dioxolan-4-ylmethylthio]phenyl]acetamide, which is deacylated with NaOH in refluxing i-PrOH to give cis-4-[2-(2,4-dichlorophenyl)-2-(1H-imidazol-1-yl-methyl)-1,3-dioxolan-4-ylmethylthio]benzenamine (VII). This compound is converted with ethylchloroformate (II) into the title compound which is isolated as the monohydrochloride on treatment with i-PrOH / HCl.
