참여 물질

반응 단계

To a solution of nicotinic acid hydrazide (35 mg, 0.25 mmol) in DMF (5 mL) was added triethylamine (88 μL, 0.64 mmol), 5-chloro-1H-pyrrolo[2,3-c]pyridine-2-carboxylic acid (Preparation 8, 50 mg, 0.25 mmol), HOBt (34 mg, 0.25 mmol) and EDCI (50 mg, 0.28 mmol). The mixture was allowed to stir at rt for 16 h. The solvent was removed in vacuo and the residue was partitioned between water (100 mL) and ethyl acetate (100 mL). The organic layer was dried (MgSO4) and concentrated in vacuo to give an oil, which was purified by flash chromatography on silica gel (dichloromethane/methanol, 9/1) to give the title compound. m/z (ES+)=316 [M+H]+; RT=2.62 min.
