Conditions

Temperature: 100 °C

Procedure

526 mg of 11β-fluoro-3-hydroxy-7α-[5-(methyl-amino)-pentyl]-estra-1,3,5(10)-trien-17-one and 127 mg of iodononane are dissolved in 5 ml of anhydrous DMF and stirred for 4 hours at a bath temperature of 100° C. For working-up, the batch is added to semi-saturated sodium bicarbonate solution, extracted 3 times with methylene chloride, dried on magnesium sulfate and concentrated by evaporation in a vacuum. Preparative column chromatography yields 85 mg of 11β-fluoro-3-hydroxy-7α-{5-[methyl-nonyl-amino]-pentyl}-estra-1,3,5(10)-trien-17-one as a foam.
