With acetic acid; In methanol;Reflux; | General procedure: Isatin based Schiff bases (1-20) were synthesized in three steps,first an esterification carried out by reacting different carboxylicacid with methanol in sulphuric acid (2-3 ml) under reflux conditionfor 12-16 h. The completion of reaction was monitored byTLC. After completion of reaction, reaction mixture was extractedwith hexane to obtained pure esters. Then esters were refluxedwith hydrazine hydrate in methanol with few drops of glacial aceticacid for 3 h. After completion of reaction, reaction mixture waswashed with chloroform to obtained different hydrazides. Thesehydrazides (1mmole) each were than treated with different Isatin(1mmole) in methanol having catalytic amount of glacial acetic acidfor 2-4 h. Reaction completion was monitored through periodicTLC. After completion of reaction, reaction mixture was washedwith n-hexane to obtain our desired products (1-20). The structureof all compounds was established through EI-MS and 1H NMR. |
