Procedure

To a mixture of ethyl 3-aminopropionate hydrochloride (23 mg, 0.19 mmol), (+/−)-4-[4,4,4-trifluoro-1-({6-[4-(trifluoromethyl)-1H-pyrazol-1-yl]pyridin-3-yl}amino)butyl]benzoic acid (44 mg, 0.096 mmol), hydroxybenzotriazole hydrate (15 mg, 0.096 mmol), and triethylamine (55 ul, 0.39 mmol) in dichloromethane (0.96 ml) was added 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (21 mg, 0.11 mmol). The mixture was stirred for 2 hours at ambient temperature. The reaction was diluted with water and the organic layer was separated. The aq. layer was extracted with dichloromethane (2×) and the combined organic layers were dried over sodium sulfate, filtered, and concentrated in vacuo. The crude material was used without further purification.
