Versuchsvorschrift

To 13β-ethyl-3-methoxy-gona-1,3,5(10)-trien-17β-ol (1.0 g.) in 1-methoxypropan-2-ol (100 cc.) add liquid ammonia (200 cc.), followed by lithium metal (1.2 g.) in small pieces with stirring. After discharge of the blue color add an excess ammonium chloride, followed by water; filter off the crude 13β-ethyl-3-methoxy-gona-2,5(10)-dien-17β-ol and dry, m.p. 98°-104°. No selective ultra-violet absorption beyond 220 mμ; infrared absorption peaks at 3.03, 5.92, 6.01 μ.
