Reaction Steps

5.295 g of N-chlorosuccinimide is added at 60° C. under an inert atmosphere to a solution of 13.6 g of 11β-[4-(phenylmethoxy)phenyl]-estra-4,9-diene-3,17-dione in 120 ml of dimethylformamide, agitation is carried out for 10 minutes then the reaction medium is poured into a saturated aqueous solution of NaCl, followed by extraction, washing, drying and evaporating under reduced pressure until the crude product is obtained (m=19.128 g). A second trial is carried out, the crude products are collected and purified by chromatography eluting with an ethyl acetate-cyclohexane mixture 30/70. 23.28 g of expected pure product is obtained. (Rf ACOET/cyclohexane 30/70=0.19).
