Reaction Steps

Add 3-phenylpropionyl chloride (0.5 g.) in benzene (1.5 cc.) with swirling to 13β-isobutyl-17β-hydroxy-gon-4-en-3-one (0.5 g.) in pyridine (2 cc.) at -20°. Store the mixture at -10° for 18 hours, add water and extract the product with ether. Wash, dry and evaporate the extracts to give a residue and recrystallize from methanol to give the title compound, m.p. 101°-106°; ultraviolet absorption peak at 240 mμ (ε15,300); infrared absorption peaks at 5.75, 5.95 μ.
