実験手順

17α-Ethynyl-17β-hydroxy-6β-(N-phenyl-N-ethylaminomethyl)-16-methyleneandrosta-4-en-3-one (Example 5) in THF (20 ml) are mixed. Degassed hydrochloric acid (6N, 55 ml plus 20 ml THF) are added. The mixture is stirred overnight at 20°-25° under nitrogen, at which time TLC shows the reaction to be complete. Water (110 ml) is added, the mixture filtered, the solids washed with 10% hydrochloric acid, twice with water, once with 5% sodium bicarbonate, and three times with water to neutrality. Solids were then dried under nitrogen overnight to give the title compound.
