Reaction Conditions

Reaction Steps

To a stirred solution of 0.55 g (2.85 mmol) of (4-chloro-2-methyl-phenyl)-hydrazine, in acetic acid (5 ml), was added 0.34 g (2.91 mmol) of ethyl pyruvate. The mixture was stirred 2 hours at 35° C., poured onto an aqueous solution of sat. NaHCO3 and then extracted with ethyl acetate. The combined organic phases were dried over Na2SO4 and concentrated in vacuo, to afford 0.702 g (97%) of 2-[(4-chloro-2-methyl-phenyl)-hydrazono]-propionic acid ethyl ester as a light orange solid.
