Procedure

Dissolve 13β-ethyl-3-methoxygona-1,3,5(10),8,14-pentaen-17-one (2 g) in dioxan (50 cc) containing Raney nickel (ca. 0.5 g) of moderate activity and shake with hydrogen until 160 cc., the amount corresponding to one molecular proportion has been absorbed. Recrystallize the isolated product from methanol to obtain the title product (1.2 g), m.p. 110°-125°; ultraviolet absorption peak at 280 mμ (ε13,200).
