K.] Swami Vivekanand Sr Coll, Dept Chem, Mantha, Maharashtra, India in 2021, Cited 48. Category: phthalazines. The Name is 4-Nitrobenzoic acid. Through research, I have a further understanding and discovery of 62-23-7
In the present investigation, we have reported the synthesis of a series of novel 3-(5-substituted-[1,3,4] oxadiazol-2-yl)-1H-indazole in good yields. 1H-indazole-3-carboxylic acid is converted to their respective esters, which on reaction with hydrazine hydrate afford 1H-indazole-3-carboxylic acid hydrazide. The reaction between 1H-indazole-3-carboxylic acid hydrazide with different substituted benzoic acids in the presence of cyclization agent phosphorus oxychloride gave aimed products in good yields.
Category: phthalazines. About 4-Nitrobenzoic acid, If you have any questions, you can contact Raut, SV; Tidke, AD; Dhotre, BK; Pathan, MA or concate me.
