Reaction Steps

4-{2-[4-(2,6-Difluoro-benzoylamino)-1H-pyrazol-3-yl]-1H-benzimidazol-5-yloxymethyl}-piperidine-1-carboxylic acid tert-butyl ester (0.024 g, 0.043 mmol) (prepared in a manner analogous to Example 130) was treated with 1:1 TFA:DCM (2 ml) for 20 min. The solution was reduced in vacuo and azeotroped with toluene (×3). Purification by preparative LC/MS gave 2,6-difluoro-N-{3-[5-(piperidin-4-ylmethoxy)-1H-benzimidazol-2-yl]-1H-pyrazol-4-yl}-benzamide as a white solid (8 mg, 41%). (LC/MS: Rt 1.99, [M+H]+ 453.06).
