실험 절차

To a solution of 7.5 g of α-formylpropionic acid ethyl ester in 50 ml ethanol were added dropwise 10.9 g 3,4-dichlorobenzylhydrazine. After stirring overnight at room temperature, the solvent was distilled off in a vacuum and the solid residue was recrystallized from ethanol. m.p. 156° C., 9.3 g (64% of theory).
