| Abstract: | Phenylglyoxylic acid ethyl ester was got via hydrolysis and esterification from benzoyl nitrile in existence of anhydride.Then it was reacted with acetylhydrazine to synthesize phenylglyoxylic acid methyl ester 2-acetylhydrazones in existence of p-toluenesulfonic acid.Finally,its yield(base on benzoyl nitrile) was 76.09%,the purity was 99.34 %,and the structure was confirmed by IR and 1h Nmr. |
