Reaction Steps

A mixture of 5α-pregna-2,16-diene-11,20-dione (60 g), hydroxylammonium chloride (21 g) and anhydrous pyridine (240 ml) was left to stand at room temperature overnight before diluting with ice and water. The precipitate obtained was collected by filtration, washed with water and dried in vacuo at 80° (62 g.). Crystallisation from ethyl acetate afforded the title compound, m.p. 168°-182°, [α]D +137°.
