参考标题:2H-Benzimidazoles (Isobenzimidazoles). Part 7. A New Route To Triclabendazole [5-Chloro-6-(2,3-Dichlorophenoxy)-2-Methylthio-1H-Benzimidazole] And Congeneric Benzimidazoles 作者:Brian Iddon,Peter Kutschy,Andrew G. Robinson,Hans Suschitzky,Walter Kramer,Franz A. Neugebauer 摘要:A New Synthesis Of The Selective Anthelmintic Agent Triclabendazole 7 From The Readily Available 5,6-Dichloro-2H-Benzimidazole-2-Spirocyclohexane 2 By Simple Steps Is Described. Analogous Benzimidazoles Difficult To Prepare By Conventional Methods Are Similarly Obtained. Triclabendazole Can Exist As A Low-Melting Metastable Solid (M.P. 85-90-Degrees-C) Convertible By Heating Or Recrystallisation From Ethanol Into Its Stable Form (M.P. 1 76-1 78-Degrees-C).
