1,1'-Thiocarbonyldiimidazole → HCID 14013074, compound

Participants

Reaction Steps

A mixture of 6 parts of N1 -[2-[4-[[1-[(4-fluorophenyl)methyl]-1H-benzimidazol-2-yl]methyl]-1-piperidinyl]ethyl]-1,2-benzenediamine, 2.7 parts of 1,1'-thiocarbonylbis[1H-imidazole] and 90 parts of tetrahydrofuran was stirred and refluxed for 1 hour. The reaction mixture was evaporated. The residue was purified by column chromatography over silica gel using a mixture of trichloromethane and methanol (95:5 by volume) as eluent. The pure fractions were collected and the eluent was evaporated. The oily residue was stirred in acetonitrile. The product was filtered off and crystallized from ethanol. The product was filtered off and dried, yielding 2.8 parts (41.5%) of 1-[2-[4-[[1-[(4-fluorophenyl)methyl]-1H-benzimidazol-2-yl]methyl]-1-piperidinyl]ethyl]-1,3-dihydro-2H-benzimidazole-2-thione; mp. 157.1° C. (493).
