Versuchsvorschrift

To a solution of 2-{3-[2-(1-{[3,5-bis(difluoromethyl)-1H-pyrazol-1-yl]acetyl}piperidin-4-yl)-1,3-thiazol-4-yl]-4,5-dihydro-1,2-oxazol-5-yl}benzoic acid (105 mg) in dichloromethane (10 ml) are added, at room temperature, cyclopropanamine (11 mg), 4-dimethylaminopyridine (2 mg) and 1-ethyl-3-(3′-dimethylaminopropyl)carbodiimide (37 mg). The mixture is stirred at room temperature for 3 hours and then admixed with water. The aqueous phase is removed and extracted with ethyl acetate. The combined organic phases are dried over sodium sulphate and concentrated under reduced pressure. The residue is purified by chromatography. This gives 2-{3-[2-(1-{[3,5-bis(difluoromethyl)-1H-pyrazol-1-yl]acetyl}piperidin-4-yl)-1,3-thiazol-4-yl]-4,5-dihydro-1,2-oxazol-5-yl}-N-cyclopropylbenzamide (78 mg).
