Reaction Steps
The compound 7α-methylestr-4-en-3α,17β-diol 17-acetate is dissolved in anhydrous dioxane and treated with pyridine, p-toluenesulfonate and cyclohexanone methyl enolether. Stirring is continued for a period of 3 hours. The solvent is removed in vacuo and the residue is crystallized from pentane resulting in the formation of the desired 7α-methyl-3α-(1'-methoxycyclohexyloxy)estr-4-en-17β-ol acetate.
