Reaction Steps

A solution of 102 g of 15α-hydroxy-18-methyl-4-estrene-3,17-dione in 500 ml of pyridine is combined under ice cooling with 50.9 ml of benzoyl chloride and stirred for one hour under cooling. Then 9 ml of water is added dropwise and the mixture is stirred for another hour. The reaction solution is then stirred into ice water, the thus-formed precipitate is suctioned off, washed with water, and dried, thus obtaining 146 g of crude 15α-benzoyloxy-18-methyl-4-estrene-3,17-dione.
