Reaction Steps

(1-Chloro-2-methyl-propenyl)-dimethylamine (20 μl) is added to a mixture of 2-{2,6-dichloro-3-[(2,2-dimethyl-propionylamino)-methyl]-phenylamino}-6-(2,2-difluoro-ethoxy)-1-methyl-1H-benzimidazole-5-carboxylic acid (53 mg, 0.10 mmol) in 1.0 mL acetonitrile and it is stirred 15 min at rt. The crude acid chloride solution is added to a mixture of 2,4-dichloroaniline (16 mg, 0.10 mmol), pyridine (24 μL, 0.30 mmol) and acetonitrile (1.0 mL) and it is stirred over the weekend at 60° C. The solvent is removed in vacuo and the residue is dissolved in 2 mL of a 9:1 DMF/water-solution and is purified via preparative HPLC.
