To a solution of (11β,16α,17β)-17-cyclopropylcarbonyl-16-methyl-11-[4-(3-pyridinyl)phenyl]estra-4,9-dien-3-one (40 mg, 0.081 mmol) in acetonitrile (1 mL) were added 2 N hydrochloric acid (40 μL) and water (5 mL). Lyophilisation of this mixture gave 11β,16α,17β)-17-cyclopropylcarbonyl-16-methyl-11-[4-(3-pyridinyl)phenyl]estra-4,9-dien-3-one hydrochloride in quantitative yield (40 mg, 0.08 mmol). 1H NMR (400 MHz, CDCl3): δ 0.34 (s, 3H), 0.80-2.85 (m, 24H), 4.47 (d, J=7 Hz, 1H), 5.81 (s, 1H), 7.31-7.35 (m, 2H), 7.51-7.55 (m, 2H), 7.64 (dd, J=8 and 5 Hz, 1H), 8.18 (dt, J=8 and 1 Hz, 1H), 8.62 (d, J=5 Hz, 1H), 8.90 (d, J=1 Hz, 1H).
