Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 4-Bromobenzohydrazide | HCID 22219 | — |
| Reactant | Ethyl orthoformate | HCID 31214 | — |
| Product | 2-(4-Bromophenyl)-1,3,4-oxadiazole | HCID 715120 | — |
Reaction Steps
12.3 mmol of 4-bromo-benzoic acid hydrazide were dissolved in 26 ml of triethyl orthoformate. The reaction mixture was stirred overnight at 140°, evaporated and the residue crystallized from ethanol to give the title compound as a colorless solid. MS (m/e): 225.0 (MH+, 100%)
