3-Chloro-4-fluoroaniline → N-(3-Chloro-4-fluoro-phenyl)-2-{2,6-dichloro-3-[(2-fluoro-2-methyl-propionylamino)-methyl]-phenylamino}-6-[4-trifluoromethyl-piperidinyl]-1-methyl-1H-benzimidazole-5-carboxylic acid amide

Participants

Reaction Steps

A mixture of 2-{2,6-dichloro-3-[(2-fluoro-2-methyl-propionylamino)-methyl]-phenylamino}-6-[4-trifluoromethyl-piperidinyl]-1-methyl-1H-benzimidazole-5-carboxylic acid (60 mg, 0.100 mmol), (1-chloro-2-methyl-propenyl)-dimethylamine (33 mg, 0.25 mmol), DIPEA (86 μL, 0.50 mmol) and MeCN (2 mL) is stirred for 20 min. This mixture is added to 3-chloro-4-fluoro-aniline (0.200 mmol) and it is stirred overnight at rt. The mixture is directly purified via reverse phase HPLC. Yield: 39 mg. HPLC Rt=0.607 min (method F). MS m/z: 731 [M+H]+.
