実験手順

A mixture of 11.3 parts of 1-[(4-fluorophenyl)methyl]-N-[1'-(phenylmethyl)-[1,3'-bipiperidin]-4-yl]-1H-benzimidazol-2-amine and 200 parts of methanol was hydrogentated at normal pressure and at room temperature with 2 parts of palladium-on-charcoal catalyst 10%. After the calculated amount of hydrogen was taken up, the catalyst was filtered off and the filtrate was evaporated. The residue was suspended in 2,2'-oxybispropane. The product was filtered off and dried, yielding 8.5 parts (91.5%) of N-([1,3'-bipiperidin]-4-yl)-1-[(4-fluorophenyl)methyl]-1H-benzimidazol-2-amine (intermediate 72).
