PROCEDURE

实验过程

The 1β,2β-methylene-5-androstene-3β,17β-diol is dissolved in acetone and Jones reagent added until a persistent yellow-orange color appears. After stirring at room temperature for ten minutes the mixture is poured onto ice-water and the precipitate is collected by filtration. The precipitate is dissolved in a solution of sodium methoxide in methanol and stirred for a period of 30 minutes at room temperature. The methanol is removed and the residue triturated with water. The solid which results is filtered and crystallized from acetone to yield 1β,2β-methylene-4-androstene-3,17-dione.
