Reaction Steps

A mixture of 2.7 parts of 2-chloroacetonitrile, 19.5 parts of N-(4-piperidinyl)-1-(3-pyridinylmethyl)-1H-benzimidazol-2-amine trihydrobromide, 13 parts of sodium carbonate and 135 parts of N,N-dimethylformamide was stirred and heated for 3 hours at 50° C. The reaction mixture was poured onto water and extracted with dichloromethane. The extract was dried, filtered and evaporated. The residue was crystallized from acetonitrile, yielding 6 parts (50%) of 4-[[1-(3-pyridinylmethyl)-1H-benzimidazol-2-yl]amino]-1-piperidineacetonitrile hemihydrate; mp. 204.5° C. (intermediate 73).
