Reaction Steps

A solution of 1.64 g of 17β-acetoxy-7α-(5-methylaminopentyl)-3-(tetrahydropyran-2-yloxy)-estra-1,3,5(10)-triene in 25 ml of absolute DMF is stirred with 159 mg of 80% sodium hydride under nitrogen for 2 hours at room temperature. 1.43 g of 3-chloro-propyl4,4,5,5,5-pentafluoropentylsulfide in 7 ml of absolute DMF is then added in drops and then stirred for 22 more hours at 80° C. The reaction solution is then diluted with ethyl acetate, washed with water, dried, concentrated by evaporation, and the residue is chromatographed on silica gel. 820 mg of 17β-acetoxy-7α-{5-[N-methyl-N-3-(4,4,5,5,5-pentafluoropentylthio)-propylamino]-pentyl}-3-(tetrahydropyran-2-yloxy-estra-1,3,5(10)-triene is obtained as oil.
