1-(4-fluorophenylmethyl)-N-[1-(2-isothiocyanatoethyl)-4-piperidinyl]1H-benzimidazol-2-amine → HCID 20222937, compound

Participants

Reaction Steps

A mixture of 20 parts of N-[(3,4-dichlorophenyl)methyl]-1,2-benzenediamine, 33 parts of 1-[(4-fluorophenyl)methyl]-N-[1-(2-isothiocyanatoethyl)-4-piperidinyl]-1H-benzimidazol-2-amine and 450 parts of tetrahydrofuran was stirred and refluxed overnight. 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, yielding 40 parts (78.9%) of N-[2-[[(3,4-dichlorophenyl)methyl]amino]phenyl]-N'-[2-[4-[[1-[(4-fluorophenyl)methyl]-1H-benzimidazol-2-yl]amino]-1-piperidinyl]ethyl]thiourea (199).
