Chlorzoxazone → 2,5-Dichlorobenzooxazole
Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Chlorzoxazone | HCID 2733 | — |
| Reactant | 6-Chloro-2,3-dihydrobenzoxazol-2-one | HCID 29858 | — |
| Product | 2,5-Dichlorobenzooxazole | HCID 10397578 | — |
Reaction Steps
If the process is carried out as in Example 1, but, instead of 6-chlorobenzoxazolin-2-one, the same amount of 5-chlorobenzoxazolin-2-one is used, then about 130 g, corresponding to 69% of theory, of 2,5-dichlorobenzoxazole, melting point 46°-48° C., are obtained.
