Procedure

To a mixture of ethyl 3-aminopropionate hydrochloride (31 mg, 0.27 mmol), (+/−)-4-(1-{[6-(4-cyclopropyl-1H-pyrazol-1-yl)pyridin-3-yl]amino}butyl)benzoic acid (0.050 g, 0.13 mmol), hydroxybenzotriazole hydrate (0.020 g, 0.13 mmol), and triethylamine (76 ul, 0.55 mmol) in dichloromethane (1.3 ml) was added 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (38.9 g, 201 mmol) (28 mg, 0.15 mmol) at rt. The mixture was stirred for 2 hours at ambient temperature. The reaction was diluted with water and the organic layer was separated. The aqueous 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.
