Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Semicarbazide hydrochloride | HCID 11236 | — |
| Reactant | 5-Bromo-1-(2-diisopropylaminoethyl)isatin | HCID 13934415 | — |
| Product | HCID 178457373 | HCID 178457373 | 72.6% |
Reaction Steps
By using 5-bromo-1-(2-diisopropylaminoethyl)isatin and semicarbazide hydrochloride, a method analogous to that described in Example 4 was carried out to obtain (E)-5-bromo-1-(2-diisopropylaminoethyl)isatin 3-semicarbazone having a melting point of 149°-153° C. (yield: 72.6%, recrystallizing solvent: chloroform-hexane).
