Reaction Steps

The procedure described in Example 10 hereinbefore was repeated except that 1 gram of 3-isobutoxy-13β-methylgona-1,3,5(10)-trien-17-one was substituted for the 3-n-propoxy-13β-methylgona-1,3,5(10)-trien-17-one that was used in that example. In this manner, 0.8 gram of 3-isobutoxy-13β-methylgona-1,3,5(10),9(11)-tetraen-17-one was obtained after distillation of the dichloromethane from the electrolyzed solution and precipitation by adding a small amount of water to the remaining solution. This compound, after recrystallization from a mixture of dichloromethane and methanol, had a melting point of 107°-108° C. and a specific optical rotation of +257.5° at a temperature of 25° C. for the sodium D line.
