Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Hydrazine hydrate (1:1) | HCID 24654 | — |
| Reactant | Ethyl 3-bromobenzoate | HCID 90488 | — |

| Product | m-Bromobenzohydrazide | HCID 520941 | 86% |
Reaction Steps
After 10 grams (44 mmol) of ethyl-3-bromobenzoate were placed into a 200 mL, three-neck flask, 50 mL of ethanol was added thereto and the mixture was stirred; 12 mL of hydrazine monohydrate was added, this mixture was stirred at 78° C. for 5 hours, and the contents of the flask were reacted together. After the reaction was completed, a solid was precipitated out with the addition of water to the reaction solution. The precipitate solid was removed by suction filtration. With the suction-filtered solid being placed into approximately 500 mL of water and washed and a solid removed by suction filtration, 8.1 grams of a white-colored solid, which was the objective of the synthesis process, were obtained at a yield of 86%.
