반응 단계

A solution of 2.04 g (10.3 mmol) of 3-aminoquinuclidine dihydrochloride, 2.70 g (10.3 mmol) of 4-amino-3-iodobenzoic acid, 1.39 g (10.3 mmol) of HOBt, 2.16 g (11.3 mmol) of EDC and 6.63 g (51.3 mmol) of N,N-diisopropylethylamine in 150 ml of DMF was stirred at room temperature for 16 h. 300 ml of water were added, and the aqueous phase was extracted three times with 300 ml of ethyl acetate each time. The combined organic phases were dried over sodium sulfate and the solvent was distilled off in vacuo. The residue was purified on a flash column (mobile phase: dichloromethane/methanol/triethylamine 90:10:0.2). 3.45 g (87%) of the desired title compound were obtined.
