Abstract

The invention comprises 3-keto-11b -hydroxy-4, 17(20)-pregnadien-21-al and the preparation thereof by reacting 11b ,21-dihydroxy-4, 17(20)-pregnadien-3-one with manganese dioxide in an organic solvent, e.g. acetone, carbon tetrachloride and ethyl acetate. The reaction may be effected between 0 DEG and 100 DEG C. Specification 749,199 is referred to.
