Abstract
The invention comprises 3-acetoxy-11-keto-bisnorcholanic acid and the methyl ester thereof, and the preparation of the acid by treating 3 - acetoxy - 11 - keto - D 22 - ergostene with ozone, and oxidizing the resulting ozonide with chromic acid, and when the methyl ester is required, the acid is esterified with diazomethane. One detailed example is given.
