Reaction Steps

A solution of 2 g of 7α-(5-bromopentyl)-11β-fluoro-estra-1,3,5(10)-triene-3,17β-diol in 20 ml of dimethylformamide is stirred with 8 ml of a 40% aqueous methylamine solution for 3.5 hours at 80° C. Then, it is added to water, extracted three times with ethyl acetate, washed with water and common salt solution, dried on sodium sulfate and concentrated by evaporation in a vacuum. 1.77 g of 11β-fluoro-7α-[5-(methylamino)-pentyl]-estra-1,3,5(10)-triene-3,17β-diol is obtained.
