실험 절차

A mixture of 250 mg of 10-(2-propynyl)estr-4-ene-3,17-dione, and 460 mg of chloranil in 17 ml of tert-butyl alcohol is heated at reflux temperature for 3 hours. The mixture is diluted with ethyl acetate and filtered and the filtrate is washed with aqueous 1 N sodium hydroxide and with brine, and dried. The solvent is then evaporated and the residue is chromatographed on silica gel using ethyl acetate-hexane to give 10-(2-propynyl)estra-4,6-diene-3,17-dione. This compound has the following structural formula ##STR13##
