Reaction Steps

In a manner similar to that described in Example 1C, treat 6β,7α-dihydroxy-4-androstene-3,17-dione (150 mg.) in pyridine (5 ml.) with methanesulfonyl chloride (1 ml.) for two hours at room temperature. Isolate the resultant product in a manner similar to that described in Example 1C to obtain 180 mg. of 6β,7α-dimethanesulfonyloxy-4-androstene-3,17-dione which is used without further purification in the following step 31C.
