反応手順

A solution of 486 mg of 11β-fluor-7α-(5-iodopentyl)-estra-1,3,5(10)-triene-3,17β-diol in 10 ml of 1-methyl-2-pyrrolidinone is stirred with 600 mg of methyl-(3-phenoxy-propyl)-amine for 3 hours at a bath temperature of 80° C. Then, the batch is added to saturated sodium chloride solution, extracted with ether, dried on sodium sulfate, concentrated by evaporation in a vacuum and chromatographed on silica gel with methylene chloride/methanol/ammonia. 443 mg of 11β-fluoro-7α-{5-[methyl-(3-phenoxy-propyl)-amino]-pentyl}-estra-1,3,5(10)-triene-3,17β-diol is obtained as a foam [α]D=+47° (c=0.5 in CHCl3).
