Participants

Reaction Steps

A mixture of 1.1 parts of isocyanatomethane, 6.76 parts of 1-[(4-fluorophenyl)methyl]-N-[1-[2-[2-thiazolylamino]ethyl]-4-piperidinyl]-1H-benzimidazol-2-amine and 90 parts of tetrahydrofuran was stirred and refluxed overnight. The reaction mixture was evaporated. The residue was crystallized from acetonitrile, yielding 4.5 parts (59%) of N-[2-[4-[[1-[(4-fluorophenyl)methyl]-1H-benzimidazol-2-yl]amino]-1-piperidinyl]ethyl]-N'-methyl-N-(2-thiazolyl)urea; mp. 171.9° C. (compound 103).
