Procedure

A solution of 22 g of 19-hydroxyandrost-4-ene-3,17-dione, 18 g of 1-adamantanecarboxylic acid chloride, and 29 ml of pyridine in 2.2 liters of toluene is refluxed overnight. The reaction mixture is cooled, and the toluene layer is washed with water, dried over magnesium sulfate and filtered then the solvent is removed. The resulting residue is crystallized from methanol to give 19-(1-adamantanylcarbonyloxy)androst-4-ene-3,17-dione, M.P. 161°-163° C.
