Procedure

At room temperature, a solution of 460 mg. of p-nitroperbenzoic acid in 3 ml. of tert.-butanol and 0.6 ml. of ethylene chloride is gradually added to 600 mg. of 3-acetoxy-18-methyl-1,3,5(10),16-estratetraene in 20 ml. of ethylene chloride. After 18 hours, the crude product is worked up as described in (A) and purified by preparative layer chromatography (eluent: hexane/ethyl acetate = 7 : 3). In this way, 490mg. of 3-acetoxy-16α,17α-epoxy-18-methyl-1,3,5(10)-estratriene is isolated as an oily product.
