The method used in research is utilizing water as solvent instead of any other organic solvent. In addition, lab-made microwave was used instead of hot plate or reflux method. P-hydroxy ethyl benzoate was treated directly with hydrazine hydrate in microwave oven which gave hydrazide derivative in a very short time; hydrazide derivative (1) was reacted with some carbonyl compounds (aldehyde derivatives) to produce of some Schiff base derivatives (compounds 2-14). None of these azomethine derivatives exceeded 10 minutes in lab-made micro wave and using water as solvent. Compounds (2-14) were treated with acetic anhydride in microwave oven to synthesized of some 1,3,4-oxadiazole derivatives (15-23). All compounds high yield, short time, low cost in comparison with traditionally methods. The prepared compounds were characterized by melting points, 1H-NMR, and FT-IR. %U https://www.chemmethod.com/article_153919_ee3c771a3eb727db3164cfba0609ba39.pdf
