3-Pyridinemethanamine → HCID 13588107, compound

Participants

Reaction Steps

A mixture of 1 part of 3-pyridinemethanamine, 3.9 parts of 1-(4-fluorophenylmethyl)-N-[1-(2-isothiocyanatoethyl)-4-piperidinyl]-1H-benzimidazol-2-amine and 45 parts of tetrahydrofuran was stirred for 4 hours at room temperature. The reaction mixture was evaporated in vacuo. The residue was purified by column-chroratography over silica gel using a mixture of trichloromethane and methanol (94:6 by volume) as eluent. The pure fractions were collected and the eluent was evaporated. The residue was crystallized from a mixture of 2-propanone and 2,2'-oxybispropane, yielding 3.4 parts (65.7%) of N-[2-[4-[[1-[(4-fluorophenyl)methyl]-1H-benzimidazol-2-yl]amino]-1-piperidinyl]ethyl]-N'-(3-pyridinylmethyl)thiourea; mp. 147.2° C. (compound 102).
