반응 단계

A solution of EDCI (66 mg, 0.35 mmol) in anhydrous DMF (2 mL) was added to a stirred solution of furo[3,2-c]pyridine-2-carboxylic acid (45 mg, 0.28 mmol) in anhydrous DMF (1 mL). After 1 h, the mixture was treated with a solution of DMAP (6 mg, 0.05 mmol) and 4-mercaptopiperidine-1-carboxylic acid tert-butyl ester (50 mg, 0.23 mmol), before being stirred for an additional 16 h. The DMF was removed under reduced pressure, then the residue was purified by flash chromatography (IH-EtOAc, 1:1 to 3:7) to furnish the title compound: RT=3.34 min; m/z (ES+)=363.1 [M+H]+.
