Procedure

To a stirred and heated (60° C.) suspension of 14 parts of 1-(2-pyridinylmethyl)-N-(3-pyrrolidinyl)-1H-benzimidazol-2-amine dihydrochloride and 9.5 parts of sodium carbonate in 113 parts of N,N-dimethylformamide were added dropwise 3.2 parts of 2-chloroacetonitrile. Upon completion, stirring was continued for 3 hours at 60° C. After cooling, the mixture was poured into ice water and the product was extracted six times with methylbenzene. The combined organic layers were washed with water, dried, filtered and evaporated, yielding 11 parts (87%) of 3-[[1-(2-pyridinylmethyl)-1H-benzimidazol-2-yl]amino]-1-pyrrolidineacetonitrile as a residue (compound 133).
