실험 절차

N-(3-Dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (EDC) (4.47 g, 23.3 mmol), 1-hydroxybenzotriazole hydrate (HOBt) (3.57 g, 23.3 mmol) and triethylamine (Et3N) (4.5 ml, 32.3 mmol) were successively added to a solution of 2-(3-(4-fluorophenyl)-1H-pyrazol-1-yl)nicotinic acid (6.0 g, 21.8 mmol) and 4-ethoxy-3-hydroxy-4-oxo-1-phenylbutan-2-aminium chloride (6.60 g, 25.4 mmol) in dichloromethane (300 ml) at 5° C., and the mixture was stirred at 5° C. for about 5 minutes. A pH of 10 was adjusted by adding 6 ml Et3N, the mixture stirred for 1 h at 5° C. and then overnight at room temperature. The mixture then was concentrated under reduced pressure, poured into 1000 ml of water, the precipitate formed was filtered off with suction and dried in vacuo to give 7.8 g, which were treated 100 ml of methyl-tert.butylether to give 7.39 g of the desired product; ESI-MS [M+H]+: 489.2.
