反応手順
75.7 g of hydrochloric salt of parachlorophenylhydrazine was dissolved into 350 ml of water. 37.2 g of pyruvic acid was added into the solution. After stirring for 30 minutes at 70° C. while heating, and then cooling, precipitated crystals were filtered out, washed, and dried. These crystals were recrystallized from isopropyl acohol to obtain 57 g of 2-(p-chlorophenylhydrazono)propionic acid having a melting point of 196° to 197° C. (decomposed).
