| Reactant | 1,1'-Biphenyl, mixt. with 1,1'-oxybis(benzene) | HCID 24670 | — |
| Reactant | HCID 70540197 | HCID 70540197 | — |
| Product | HCID 56615316 | HCID 56615316 | 63.4% |
Reaction Steps
One gram of 17α-acetoxy-12α-chloro-1α,2α-methylene-4,6-pregnadiene-3,20-dione is treated analogously to Example 1 in "Dowtherm" for 1 hour at 280° C. and worked up. Recrystallization from isopropyl ether yields 500 mg of 12α-chloro-1α,2α-methylene-4,6,16-pregnatriene (61% of theory).
