Versuchsvorschrift

Add 13β-Ethyl-3-methoxy-gona-1,3,5(10)-trien-17β-ol (0.5 g.) in tetrahydrofuran (50 cc.) to stirred liquid ammonia (150 cc.), followed by lithium foil (0.5 g.) and then add ethanol (6 cc.) during 20 minutes. When the blue color is discharged, add water and work up the product with ether, to yield 13β-ethyl-3-methoxy-gona-2,5(10)-dien-17β-ol as a solid (0.47 g.).
