Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Hydrazine hydrate (1:1) | HCID 24654 | — |
| Reactant | Thionordiazepam | HCID 826706 | — |
| Product | 7-Chloro-2-hydrazinyl-5-phenyl-3H-1,4-benzodiazepine | HCID 12390874 | — |
Reaction Steps
A mixture of 7-chloro-1,3-dihydro-5-phenyl-2H-1,4-benzodiazepine-2-thione and hydrazine hydrate is allowed to stand for 72 hours at about 25° C. After evaporation of the ethanol, the solid products obtained are recrystallized from methylene chloride-benzene to give 7-chloro-2-hydrazino-5-phenyl-3H-1,4-benzodiazepine of melting point 204°-207° C.
