Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 2,3-Dichloro-5,6-dicyano-1,4-benzoquinone | HCID 6775 | — |
| Reactant | 16-Methylprogesterone | HCID 134874 | — |
| Solvent | Benzene | HCID 241 | — |
| Product | HCID 54339148 | HCID 54339148 | — |
Reaction Steps
A mixture of 16α-methylprogesterone (792 mg). DDQ (575 mg) and benzene are heated at reflux for 28 hr, after 20 hr additional DDQ (70 mg) is added. After refluxing, the mixture is cooled to 20°-25°, filtered followed by basic workup (ether potassium carbonate-magnesium sulfate) to give 16α-methylpregna-1,4-diene-3,20-dione.
