Reaction Steps

526 mg of 11β-fluoro-3-hydroxy-7α-[5-(methylamino)-pentyl]oestra-1,3,5(10)-trien-17-one and 127 mg of iodononane are dissolved in 5 ml of anhydrous DMF and stirred at a bath temperature of 100° C. for 4 h. For work-up, the mixture is added to half-saturated sodium hydrogencarbonate solution, extracted 3 times with methylene chloride, dried over magnesium sulphate and concentrated in vacuo. Preparative column chromatography yields 85 mg of 11β-fluoro-3-hydroxy-7α-{5-[methyl-nonyl-amino]pentyl}oestra-1,3,5(10)-trien-17-one as a foam.
