3-Chloro-4-fluoroaniline → N-(3-Chloro-4-fluoro-phenyl)-2-{2,6-dichloro-3-[(2,2-dimethyl-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-[(2,2-dimethyl-propionylamino)-methyl]-phenylamino}-6-[4-trifluoromethyl-piperidinyl]-1-methyl-1H-benzimidazole-5-carboxylic acid (72 mg, 0.120 mmol), (1-chloro-2-methyl-propenyl)-dimethylamine (33 mg, 0.25 mmol) and MeCN (2 mL) is stirred for 20 min. This mixture is added to 3-chloro-4-fluoro-aniline (36 mg, 0.25 mmol) and DIPEA (129 μL, 0.75 mmol) in MeCN (3 mL) and it is stirred overnight. The mixture is concentrated and the residue is taken up in DMF (2 mL) and purified by reverse phase HPLC.
