A new simple and convenient method of synthesis of ethyl 1-aryl-4-formyl-1H-pyrazole-3-carboxylates from aromatic amines via diazonium salts has been developed. Hydrolysis and hydrazinolyization of these compounds has been investigated.
已经开发了一种新的简单方便的方法,该方法通过重氮盐由芳族胺合成1-芳基-4-甲酰基-1 H-吡唑-3-羧酸乙酯。已经研究了这些化合物的水解和肼解。
