실험 절차

To a stirred solution of 6-chloro-4-(isopropylamino)nicotinohydrazide (10) (200 mg, 0.35 mmol) in DCM (10 mL), Et3N (3.1 mmol, 3 equiv) was added and cooled to 0° C. Methyl 2-chloro-2-oxoacetate (0.42 mmol, 1.2 equiv) was added dropwise and stirred for 6 h at room temperature. The reaction mixture was quenched with aq. NaHCO3 solution and extracted in DCM. The organic layer was separated, dried over Na2SO4, filtered and concentrated. The crude material was purified by column chromatography through silica gel and MeOH: DCM as eluent to afford methyl 2-(2-(6-chloro-4-(isopropylamino)nicotinoyl)hydrazinyl)-2-oxoacetate.
