Reaction Steps

Hydrogenate 13β-ethyl-3-methoxy-17,17-ethylenedioxygona-1,3,5(10), 8,14-pentaene (2.0 g.) in benzene 70 cc.) at atmospheric pressure using a 5% palladium on calcium carbonate catalyst (0.70 g.). Uptake of hydrogen ceases after 150 cc. has been absorbed. Isolate the product and recrystallize from 95% ethanol to obtain the title product (1.3 g.), m.p. 135°-137°; ultraviolet absorption peak at 2.78 mμ (15,100).
