PROCEDURE

实验过程

To a solution of 1α-methyl-4-androstene-17β,19-diol dipropionate in 10% aqueous methanol is added 1 equivalent sodium bicarbonate and the solution is heated under reflux for one hour. Methanol is removed under vacuum to half volume and the concentrate is poured onto water. The solid is filtered, air dried and crystallized from hexane to give 1α-methyl-4-androstene-17β,19-diol 17-propionate.
