Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 768-05-8, name is Pyrazinoic acid hydrazide, A new synthetic method of this compound is introduced below., Computed Properties of C5H6N4O
General procedure: The 2-(3-methylbutanoyl)-1H-indene-1,3(2H)-dione neededfor the synthesis was prepared by the Claisen condensation of diethylphthlate and appropriate ketone under the inuence ofsodium methoxide according to the procedure as described inthe literature.32,33 Schi bases were synthesized by dissolving 1:1molar ratio methanolic solution of 2-(3-methylbutanoyl)-1Hindene-1,3(2H)-dione with benzoic acid, pyrazine acid, nicotinic acid, and isonicotinic acid hydrazides. The solution wasstirred and reuxed for 5-6 h. The solution was kept overnightat room temperature. The white and red color solids so obtainedwere fltered and recrystallized in methanol and chloroformsolution (1:1, v/v).
The synthetic route of 768-05-8 has been constantly updated, and we look forward to future research findings.
