実験手順

17β-Hydroxy-14α,15α-methylene-androst-4-ene-3-one (4 g) in 160 mL of toluene is stirred for 6 days at 85° C. with 3.2 g of 2,3-dichloro-5-6-dicyanobenzoquinone. The precipitate is filtered off, washed with a little toluene and the filtrates and washings are evaporated to dryness. The residue is purified by chromatography, 17β-Hydroxy-14α,15α-methylene-androsta-1,4-diene-3-one being obtained.
