실험 절차

The p-chlorophenylhydrazone of ethyl 2-oxobutanoate was prepared by adaptation of the Japp-Klingemann reaction as described by lions and Hughes (J. Proc. Roy. Soc. N. S. Wales 1939, 71: 445) to p-chloroaniline and ethyl 2-ethylacetoacetate. This phenylhydrazone was treated with HCl-ethanol according to the procedure of lions and Hughes (J. Proc. Roy. Soc. N. S. Wales 1939, 71: 445) as applied therein to the corresponding bromophenylhydrazone. The title substance was collected by filtration as an orange solid after suspending the concentrated residue in water.
