実験手順
A solution of ethyl 1,2,2-trichlorocyclopropane carboxylate (3 grams), ethanol (25 ml), and anhydrous hydrazine (0.48 grams) was heated to reflux for approximately 2 hours. The reaction mixture was cooled, the solvent was stripped from solution, and the residue was recrystallized using a small volume of ethanol to produce 1,2,2-trichlorocyclopropane carboxylic acid hydrazide (mp 122°-123° C.). The identity of the final product was confirmed by NMR analysis.
