Versuchsvorschrift

A mixture of 2-fluoroisobutyric acid (191 mg, 1.80 mmol), TBTU (578 mg, 1.80 mmol), DIPEA (1.00 mL, 5.7 mmol) and 10 mL DMF is stirred for 10 min and then the mixture is added to 2-{2,6-dichloro-3-[aminomethyl]-phenylamino}-6-[4-trifluoromethyl-piperidinyl]-1-methyl-1H-benzimidazole-5-carboxylic acid (929 mg, 1.80 mmol) in 10 mL DMF and it is stirred overnight. Then the mixture is concentrated and purified via prep HPLC.
