Reaction Steps

Dissolve 13β-ethyl-gon-4-en-17β-ol (0.29 g.) in acetone (40 cc.) and 8N-chromic acid dropwise with stirring until the solution becomes permanently orange and then add isopropanol (3 cc.) and evaporate the solution to small bulk (ca. 5 cc.). Add water and extract the mixture with ether. Wash, dry and evaporate the ethereal solution to obtain 13β-ethyl-gon-4-en-17-one (0.24 g.), m.p. 101°-102° C. Purify by recrystallization from methanol to obtain the pure product, m.p. 102.5°-103.5° C.
