Procedure

Add dl-3-methoxy-17β-hydroxy-6-methyl-13-ethylgona-1,3,5(10)-triene (6.80 g) in tetrahydrofuran (200 cc) to liquid ammonia (800 cc) containing tetrahydrofuran (250 cc). Add lithium metal (3.5 g) portionwise and stir the solution for 1.75 hours. Discharge the blue color by dropwise addition of absolute ethanol over 0.25 hours followed by water (2,000 cc). Filter, wash and dry to obtain the dl-3-methoxy-17β-hydroxy-6-methyl-13-ethylgona-2,5(10)-diene (6.5 g), m.p. 176°-182°, λ max. KBr 3.05 μ, 5.90 μ, 6.0 μ, no absorption in the ultraviolet above 220 mμ.
