Reaction Steps

Triethylamine (4 ml, 28.7 mmol) was added to a suspension of 15α-acetoxy-18-methyl-estr-4-en-3,17-dione (4 g, 11.6 mmol) in EtOH (24 ml). The mixture was heated under reflux for 2 h. It was cooled to room temperature and water (50 ml) was added. The precipitate was filtered, washed with a 6/4 EtOH/water solution and dried under vacuum. The residue was purified by flash chromatography on silica gel to afford 18-methyl-estra-4,15-dien-3,17-dione (2 g, yield: 62%).
