Procedimiento

Into a 250 ml 3-neck round bottom flask is placed 17β-Benzoyl-estra-1,3,5(10)-triene-3-carboxylic acid and an excess of sodium hydroxide. To the flask is added dimethyl sulfoxide as a solvent. The mixture is heated to reflux for 3 hours. Standard workup followed by isolation by preparative HPLC yields title compound.
