This general procedure is effective for the preparation of many types of phenylhydrazones. For example, a substituted diazo compound can be employed.2 Alkylated acetoacetic esters 8 and ethyl benzoylacetate 4 may be used. For the higher homologs, the a-formyl derivatives of ketones may be used in place of ethyl acetoacetate.6 6 Ethyl pyridylacetates may also be substituted for ethyl acetoacetate.7 The products in these cases are the phenylhydrazones of 2-acylpyridines. [Pg.85]
