반응 단계
4-Chloro-2-carboxypyridine (2.0 g), (aminomethyl)cyclopropane hydrochloride (1.7 g), 1-ethyl-3-(3-diethylaminopropyl)carbodiimide hydrochloride (WSC) (2.9 g), 1-hydroxybenzotriazole (HOBt) (2.3 g), triethylamine (2.1 ml) and tetrahydrofuran (30 ml) were stirred together at room temperature for 2 hours. Water was added, extraction was performed with ethyl acetate, and then silica gel was added to the extract and the solvent was distilled off under reduced pressure. The silica gel was charged into a dry column packed with silica gel and purified by column chromatography (hexane:ethyl acetate=4:1, followed by 2:1) to obtain 1.5 mg of the target substance as a yellow oil.
