Abstract
A simple and fast sepn. of 7α- (I) and 7β-methyl-17β-acetoxy-3-oxoandrost-4-ene (II) was performed. The high efficiency of the axially compressed columns allowed a peak resoln. comparable to the obtained under anal. conditions. I and II were isolated in high purity and almost quant. yields.
