Reaction Steps

To ethyl 3-chloro-5-formylisonicotinate (2 g, 9.36 mmol) in 60 mL of ethanol was added acetohydrazide (0.832 g, 11.24 mmol) at room temperature. The reaction mixture was stirred for 2 h. Then, the reaction mixture was mixed with DCM and water. The organic phase was washed with brine, dried and concentrated. The crude title compound was purified by chromatography (eluent: DCM/methanol) to give 220 mg (8.7%) of the title compound as orange oil.
