Reaction Steps

To 2.1 g (9.83 mmol) of ethyl 4-chloro-2-formylnicotinate in 60 mL of ethanol was added 0.874 g (11.80 mmol) of acetohydrazide at room temperature. Then, the reaction mixture was heated under reflux for 2 h. The reaction mixture was extracted with water/DCM. The organic phase was washed with brine, dried, filtrated and concentrated to give 1.95 g (73.6%) of the title compound as white solid.
