PROCEDURE
实验过程
Under argon gas, 1 g of 9α-bromo-11β-hydroxy-4-androstene-3,17-dione is agitated in 5 ml of "Dowtherm" A for 3 minutes at 250° C. To work up the reaction mixture, the solvent is removed by steam distillation, the residue is dried and recrystallized from methylene chloride-isopropyl ether, thus obtaining 635 mg of 4-androstene-3,11,17-trione, mp 214°-216° C.
