Reaction Steps

A suspension in water (150 ml) of 4-nitrophenylhydrazine (15 g, 23 mmol) and 2-oxo-propionic acid ethyl ester (12 g, 100 mmol) was left under stirring at room temperature for 6 hours. The obtained precipitate was filtered and washed to give the ethyl ester of the 2-[(4-nitrophenyl)-hydrazono]-propionic acid.
