Procedure
A mixture of 8.35 parts of thiourea, 26 parts of 2-chloro-1-[(4-fluorophenyl)methyl]-1H-benzimidazole and 400 parts of ethanol was stirred and refluxed for 5 hours. The reaction mixture was evaporated. The residue was suspended in 2,2'-oxybispropane. The precipitated product was filtered off and crystallized from ethanol, yielding 6.1 parts of 1-[(4-fluorophenyl)methyl]-1H-benzimidazole-2-thiol; mp. 194.7° C. (62).
