Reaction Steps
To a solution of 11.9 g of 11β-[4-(3-hydroxypropyl)phenyl]-estra-4.9-diene -3,17-dione prepared to preparation 1 in 100 ml of DMF, under inert atmosphere and at 60° C., 4.93 g of N-chloro succinimide is added and stirred for 10 mn at this temperature. It is poured into water, drawn off, washed, dried, evaporated under reduced pressure until 16.2 g of raw expected product is obtained that is purified by chromatography by eluting with the compound CH2Cl2/Acetone 85/15. 9.34 g of pure expected product is obtained.
