Abstract
Procedure for obtaining 6α-methyl-19-nor-progesterone, of general formula **(See formula)** characterized in that in a compound of general formula **(See formula)** where R1 means a free or catalyzed oxo group, R2 means a free or esterified hydroxy group and R3 means a hydrocarbon or carboxylic acid moiety, the aldehyde group is reduced to the methyl group, and an enolic or cetalic group, in case given existing in the obtained compounds, the corresponding keto group and/or a free hydroxy group is cleaved in position 17, if any existing in the obtained compounds, the epimer mixture obtained is caproilized and in an arbitrary step, in If given after previously enriching the 6α-epimer, the 6α-methyl compound is isolated.
