Reaction Steps
Dissolve dl-3-methoxy-6-methyl-13-ethylgona-1,3,5(10)-trien-17-one (7.0 g) in methanol (300 cc) and treat with sodium borohydride (3.0 g). After spontaneous reflux ceases, make acid with 50% aqueous acetic acid (20 cc). Pour into brine, extract with acid and isolate the dl-3-methoxy-17β-hydroxy-6-methyl-13-ethylgona-1,3,5(10)-triene (6.8 g), m.p. 150°-160°C, λ max. KBr 3.05, 6.45 μ.
