YieldReaction ConditionsOperation in experiment
To the each acylhydrazide (150 mumol, see structures on table) is added {1-[3-(4-hydroxy-phenyl)-4-phenyl-isoxazol-5-yl]-cyclopropyl}-imidazol-1-yl-methanone (150 mumol) in acetonitrile (2.5 mL). The mixtures are heated in the cavity of a microwave to 140° C. for 600 seconds. 2-Chloro-1,3-dimethylimidazolinium chloride (450 mumoles) and triethylamine (900 mumoles) is added and the reactions are heated in the cavity of a microwave to 140° C. for 600 seconds. The solvent is removed in vacuo using a Genevac EZ-2. To each reaction mixture is added methylene chloride (2 mL) and water (2 mL). The layers are separated by filtering through Phase Separator SPE (solid phase extraction) Columns. Each organic layer is filtered through a Silica (500 mg) SPE column and eluted with methylene chloride (6 mL). The solvent is removed in vacuo using a Genevac EZ-2 to obtain a sample that is then purified by reverse phase HPLC.

YieldReaction ConditionsOperation in experiment
In ethanol; at 80℃; for 3h; General procedure: 8-Methoxyquinoline-2-carbaldehyde (25, 0.534 mmol) was refluxedwith various substituted acylhydrazines (0.587 mmol, 1.1 eq) in ethanol(5-10 mL) to get acyl hydrazides of 8-hydroxyquinoline. After completionof reaction, quinoline acyl hydrazides were found as precipitateson cooling to -15 C. Precipitates were washed with coldethanol and dried under vacuum. These acyl hydrazides were used directlyfor one pot synthesis of 2,5-disubstituted-1,3,4-oxadiazole usingiodine/K2CO3 catalysed oxidative cyclization. To the acyl hydrazides(1.0 eq) in DMSO (5-10 mL), K2CO3 (3.0 eq) and iodine (1.2 eq) wereadded in sequence and refluxed at 110 C. After the completion, thereaction mixture was cooled and saturated solution of sodium thiosulfatewas added. The precipitates were collected and dried under highvacuum to get the respective compounds (33-50).

The reaction medium was poured into water and extracted with ethyl acetate. The organic layer was washed with water followed by brine solution, dried over anhydrous sodium sulphate, filtered and concentrated under reduced pressure, to obtain the pure compounds.

YieldReaction ConditionsOperation in experiment
64% With sodium cyanoborohydride; acetic acid; In tetrahydrofuran; methanol; for 52h;Reflux; An appropriate 4-halogenobenzohydrazide (1 mmol) was dissolved in 7 mL of a mixture of THF with MeOH (1:1, v/v), followed by addition of <strong>[2631-77-8]3,5-diiodosalicylaldehyde</strong> (411.3 mg, 1.1 mmol). After a complete dissolution, sodium cyanoborohydride (100 mg; 1.6 mmol) and glacial acetic acid (100 µL) were added. The mixture was heated under reflux for 4 h and then let stir for 48 h at room temperature. After this time, the reaction mixture was diluted with distilled water and let stir for 30 min. Then, the mixture was evaporated to dryness and suspended in a small volume of MeOH. After additional 2 h, the resulted precipitate was filtered off and dried to provide pure product.
