Reaction Steps
Add 13β-ethyl-17β-hydroxy-gon-4-en-3-one (0.11 g.) in dry pyridine (0.35 cc.) at -20° to 3-phenylpropionyl chloride (0.11 g.) in benzene (0.3 cc.). Keep this at -10° for 16 hours, add ice-cold water and extract with a mixture of equal volumes of ether and benzene. Wash the extracts in turn with 2N potassium hydroxide solution, water, 2N hydrochloric acid solution, and brine, and dry. Evaporate solvent to give a residue and recrystallize from a mixture of ether and ethyl acetate to obtain the title compound (0.10 g.), m.p. 135°-40°; infrared absorption peaks at 5.81, 5.99, 8.51, 13.3, 14.3 μ, showing no absorption due to hydroxyl.
