実験手順
A mixture of 39.8 parts of N-(2-aminophenyl)-N'-ethyl-N'-[I-(2-phenylethyl)-4-piperidinyl]thiourea, 15 parts of mercury oxide, 0.1 parts of sulfur and 400 parts of methanol is stirred and refluxed overnight. The reaction mixture is filtered hot over Hyflo and the filtrate is evaporated. The residue is crystallized from 4-methyl-2-pentanone. The product is filtered off and dried, yielding 14.5 parts (43%) of N-ethyl-N-[I-(2-phenylethyl)-4-piperidinyl]-1H-benzimidazol-2-amine; mp. 204.9° C.
