Procedure

reacting 4-morpholin-4-ylmethyl-benzene-1,2-diamine with 4-nitro-1H-pyrazole-3-carboxylic acid in the presence of 1-ethyl-3-(3′-dimethylaminopropyl)-carbodiimide (EDC) and 1-hydroxybenzotriazole (HOBt) in N,N-dimethyl formamide (DMF) to give 5-morpholin-4-ylmethyl-2-(4-nitro-1H-pyrazol-3-yl) 1H-benzimidazole; and (ii) reducing the nitro group by treatment with palladium on carbon under a hydrogen atmosphere; or (i) reacting the 4-amino-1H-pyrazole-3-carboxylic ester with the appropriate carboxylic acid in the presence of 1-ethyl-3-(3′-dimethylaminopropyl)-carbodiimide (EDC) and 1-hydroxybenzotriazole (HOBt) in N,N-dimethyl formamide (DMF) or with the appropriate acid chloride in the presence of triethylamine to form the 4-amide-1H-pyrazole carboxylic acid; and (ii) reacting 4-morpholin-4-ylmethyl-benzene-1,2-diamine with the appropriate 4-amide-1H-pyrazole carboxylic acid in the presence of 1-ethyl-3-(3′-dimethylaminopropyl)-carbodiimide (EDC) and 1-hydroxybenzotriazole (HOBt) in dimethyl form amide (DMF) to give the [3-(5-morpholin-4-ylmethyl-1H-benzimidazol-2-yl)-1H-pyrazol-4-yl]-amide.
