Process for the production of 4-acylamido-4, 4-dicarbalkoxy-butanalphenylhydrazone

摘要

There is provided a process for the production of 4-acylamido-4,4-dicarbalkoxy-butanalphenylhydrazones comrising adding an acylamidomalonic acid ester to acrolein in the presence of a catalyst and then reacting the 4-acylamido-4,4-dicarbalkoxy-butanal with phenylhydrazine. The catalyst is an alkali metal salt of a carboxylic acid.
