反応手順
A mixture of 2,4-dichlorophenylhydrazine (16.00 g, 0.075 mol), ethyl pyruvate (14.47 g, 10.3 mL, 0.12 mol), glacial acetic acid (0.9 mL), absolute ethanol (105 mL) was refluxed for 2 hours. After cooling at room temperature, the solid which formed was filtered and recrystallized from ethanol to give 17.0 g (83%) of the title compound, mp 118-120° C. (from ethanol).
