Versuchsvorschrift
The thiohydroxamine acid, 3-(p-methoxyphenyl)-5-phenyl-1-hydroxy-1,2-dihydroimidazole-2-thione, was prepared from the thiocarbamate in a manner similar to that used in Example I. The 3-(p-methoxyphenyl)-5-phenyl-1-hydroxy-1,2-dihydroimidazole-2-thione was recrystallized from methylene chloride/hexane to give white crystalline material. mp: 168° C.
