Procedure

6 ml of sulphuryl chloride at 10% in dichloromethane is added under an inert atmosphere, at ambient temperature to a solution of 1.08 g of 11β-[4-(2-(dimethylamino) ethoxy) phenyl]-estra-4,9-diene-3,17-dione in 11 ml of pyridine and agitation is carried out for 30 minutes at approximately −36° C. The reaction medium is poured into sodium bicarbonate, followed by extraction, washing, drying and evaporating under reduced pressure until 1.84 g of crude product is obtained, which is purified by chromatography, eluting with an ethyl acetate/triethylamihe mixture 80/20. 616 mg of expected pure product is obtained. (Rf AcOEt/TEA 8/2=0.35).
