Reaction Steps

Employing substantially the same procedure as described in Example 6, but substituting 20-hydroxy-5α-4-azapregn-1-ene-3-one and trimethylacetyl chloride for the 20-hydroxy-4-methyl-5α-4-azapregnan-3-one and 10-undecenoyl chloride, respectively, used therein, the title compound was obtained. MS M-1 calculated for C25H39NO3, mw=402.53; observed m/e 401.
