Versuchsvorschrift

2-(3-Fluoro-phenyl)-cyclopropanecarboxylic acid 2 (90 mg, 0.50 mmol) was dissolved in 10 ml DMF. 115 mg (0.6 mmol) 1-Ethyl-3-(3-dimethylaminopropyl) carbodiimide hydrochloride (EDC) and 81 mg (0.6 mmol) 1-Hydroxybenzotriazole (HOBT) were added. The mixture was stirred for 30 min at room temperature (RT). Then 97 mg (0.5 mmol) 2-Amino-3H-benzoimidazole-5-carbonitril hydrochloride 1 were added to the mixture, which was stirred for 16 h at RT. After removing the solvent in vacuo, 20 ml water were added, whereupon the mixture was extracted 3 times with 50 ml acetic acid ethylester. The organic phases were combined, dried with sodium sulfate, and evaporated to dryness. The residue was separated via preparative HPLC. The resulting clean fractions were concentrated and lyophilized. 91 mg (57%) of a colorless, amorphous solid 3 were obtained.
